Question on Point Charges?
Asked by Shrinath Sharma | 12 Aug, 2010, 09:16: PM
answered-by-expert Expert Answer
Potential due to point charge = kq/r = 9x109x5x10-7/0.1 = 45 x 103 V = 45 kV
Work done = q'V = (5x10-10)(45 x 103) =  225 x 10-7 J.

A parallel-plate capacitor has a plate area of 100c * m ^ 2 and a plate separation of 2.0 cm. has been charged up to 3000 V by a battery. Now, (i) after disconnecting the battery, (ii) keeping the battery connected, the distance between the plates is increased to 5.0 cm intensity of electric field between the plates and the energy of the capacitor. ( epsilon_{0} = 8.85 * 10 ^ - 12 * F * m ^ - 1
