If two charged plates are maintained at a potential difference of 3 kv, the work done in taking a charge of 600µc across the field is
A
0.8j
B
1.8j
C
9.0j
D
18.0j
correct option: b
Workdone = product of the charge Q, and the p.d V.
i.e Work done = QV
= 600 * 10<sup>-6</sup> *2.1 * 10<sup>3</sup><br />
=1.8j
