Two identical metal spheres A and B are connected by a metal rod. Both are initially neutral. 1.0x10^12 electrons are added tothe sphere A, then the connecting rod is removed.

Afterwards what is the charge of A and the charge ofB?

Charge on each metal sphere will be

Explanation:

We have given number of electron added to metal sphere A

As both the spheres are connected by rod so half -half electron will be distributed on both the spheres.

So electron on both the spheres

We know that charge on each electron

So charge on both the spheres will be equal to

So charge on each metal sphere will be equal to

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
