Question

Two identical metal spheres, carrying unequal positive charges, are

separated by a certain distance. They are brought in contact and again

placed at the same separation. What will happen to their charges and the

force between them​

Answer 1

Correct option is

C

more than before

Before touch the electrostatic force between them is F=

r

2

kq

1

q

2

When they are touched, the charge will flow still they have same potential. So the average charge on each sphere is q

a

=

2

q

1

+q

2

Thus, q

a

>q

1

and q

a

>q

2

So, after touch the force between them will be more than before.
