Work done by an electrostatic field in m...

Work done by an electrostatic field in moving a given charge from one point to another …… upon the chosen.

A

zero

B

positive

C

negative

D

data insufficient

Text Solution

Verified by Experts

The correct Answer is:
C
In moving a small positive charge from Q to P, work has to be done by an external agency against the electric field. Therefore, work done by the field is negative .
