What is the new charge on each sphere?
So each sphere now has −7,2×10−18 C of charge. We know that charge is quantised and that electrons carry the base unit of charge which is −1,6×10−19 C.
What happens to the charge on the two spheres?
If two spheres are connected the charges will equilibrate until equal amounts of charge are on each sphere. � This amount would be the average of the two charges. So the two spheres are qB and qD. So the three spheres are qA, qC, and qD.
How much charge is on the sphere when it is fully charged?
1 Answer. David G. Each time a set of metal spheres touch the total of their charges will be equally shared between them. The final charge on sphere C is −5.625q .
When these two spheres are made to touch with each other then final charge on bigger sphere will be?
Assertion : When two charged spheres are connected to each other by a thin conducting wire, charge flow bigger sphere to smaller sphere, if initial charges on them are same.
Reason : Electrostatic potential energy will be lost in redistribution of charges.
What is the force between two small charged spheres having charges of 2/10 − 7 C and?
What is the force between two small charged spheres having charges of 2 x 10-7 C and 3 x 10-7 C placed 30 cm apart in air? Hence, force between the two small charged spheres is 6 × 10 – 3 N.
What is the force between 2 small charged spheres?
Hence, force between the two small charged spheres is 6×10−3 N. The charges are of same nature. Hence, force between them will be repulsive.
When 2 1011 electrons are removed from a neutral metal sphere the charge on the sphere becomes?
As electrons are removed, so charge will be positive.
How do you find the magnitude of a charge in a sphere?
Which spheres are positively charged?
The left sphere ends up with a positive charge (the opposite type of charge as the balloon). The right sphere ends up with a negative charge.
What happens when two spheres are connected by a conducting wire?
If both the spheres are connected by a conducting wire, charge will flow through the wire and wire will warm up. By conservation of energy the stored energy in the system will convert into the heat energy.
How will spheres behave if they both have the same charge?
The one exception is when the two spheres have the same charge ratio that they would obtain by being brought into contact. In this case, they repel, and we derive an analytical expression for the force at contact, for any size ratio, generalizing a force formula for equal spheres obtained by Kelvin in 1853.
What can you conclude about the distribution of charge on the sphere?
The electric field generated by the positive charge possessing spherical symmetry. Therefore, one can conclude that the charge distribution is spherically symmetric.
When a positively charged sphere is brought?
When a positively charged sphere is brought near a metallic sphere, it is observed that a force of attraction exists between the two. It means that. C. nothing can be said about the charge of the metallic sphere.
How much charge can a metal sphere hold?
Solution : Radius, r = 1 cm = 0.01 m
So, capacitance of the sphere,
`C = 4pi in_0 r =(1)/(9 xx 10^(9))xx0.
What is the force between two spheres each weighing 20 kg and separated by 50 cm?
This is Expert Verified Answer G = 6.67 × 10-¹¹ Nm²/kg² m1 = m2 = 20kg. r = 50cm = 0.5m.
What is the force on the second sphere due to the first?
b) Force on second sphere due to first is 0. 2N but in opposite direction, because the charges due to same and distance is same; so force is also same.
What is the force between two charges?
According to Coulomb’s law, the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. It acts along the line joining the two charges considered to be point charges.
Is the force acting between two point electric charges q1 and q2?
This is Expert Verified Answer The force acting between the charges q1 and q2 are attractive and repulsive forces. When the product of charges are greater than zero, which means the charges are repealing each other. That means the both the charges are like charges.
Solution : Electrostatic force between the two point charges decreases when a dielectric medium is placed between them.
What is the force between two alpha particles?
The Force between two alpha particles will be equal to 90 N. Hence option 4 is correct.
When 10/19 electrons are removed from a neutral metal sphere the charge on the sphere will be?
When 1019 electrons are removed from a neutral metal plate through some process, the electric charge on it is +1.6 C.
When 10/19 electrons are removed from a neutral metal sphere the charge on the sphere becomes?
So the charge on the metal plate after the removal of the electrons will be +1.6C.
When 10 raise to 14 electrons are removed from a neutral metal sphere the charge on the square becomes?
Solution : Charge of ` 10^(14) ` electron `q= n e =10^(14) xx1. 6 xx 10^(-19) C = 1.6 xx 10^(-5) C = 16 mu C . ` As electron have been removed from metal sphere, it will acquire a positive charge of ` +16 muC .
How do you find the magnitude of a charge?
We can use the equation E = k | Q | r 2 E = k | Q | r 2 to find the magnitude of the electric field. The direction of the electric field is determined by the sign of the charge, which is negative in this case. E = k | Q | r 2 = ( 8.99 × 10 9 N ⋅ m 2 /C 2 ) | − 1.5 × 10 − 9 C | ( 0.035 m ) 2 = 1.1 × 10 4 N/C.
