Question

40mJ work is done to bring charge ‘q’ from one specific point to infinity. Potential at a specific point is -10V. (At infinity, Electric potential is taken zero). Find the value of charge.

Answer 1

Answer:

A second charge, Qx = 2Q0 , is brought to the point x = a, y = 0. ... How much work does it take to transfer charge from one to the other until they ... When a charge q (assumed positive) is on the inner sphere, the potential ... A certain capacitor stores 40 mJ of energy when charged to 100 V.
