Question

Two spheres A and B of radius 4cm and 6cm are givencharges of 80 and 404c respectively. If they areconnected by a fine wire, the amount of charge flowing fromone to the other is?​

Answer 1

1)The ratio of their volume(A:B) will be:

cube of A's radius:cube of B's radius i.e.

8:27

2) Total charge in the two will be 80+404=484 C

3) Charge in A

=8/35 of 484

4)Charge in B

=27/35 of 484

Solve it

Charge will flow from B to A because charge in B will be greater

The amount will be the difference in two i.e. charge in B - charge in A

ufff .....that all

P.S. ----- "of" means you have to multiply.

Got it???
