1.	The workdone in carrying a charge Q, once round a circle of radius R with a charge Q at the centre is-(a) \(\frac {Q_1Q_2}{4πε_0 R^2}\)(b) Zero(c) \(\frac {Q_1Q_2}{4πε_0 R}\)(d) infinite
Answer» (b) zero The electric field is conservative. Therefore, no work is done in moving a charge around a closed path in a electric field.
