Question

A and B are two hollow metal spheres of radii 50 cm and 1 m carrying charges 0.6 micro coulomb and 1 micro coulomb respectively. They are connected externally by a conducting wire. Now the charge flows from​

Answer 1

Answer:

A to B till the potentials become equal

The potential of a sphere of radius r carrying a charge q is r/kq

.

Hence potential of first sphere=V

A = 0.5m/k(0.6μC)

Potential of second sphere=V B = 1m/k(1μC)

⟹V A >V B

Hence charge flows from A to B till the potentials become equal.
