Question

For $Q<0,V<0$, work done (by the external force) per unit positive test charge in bringing it from infinity to the point is negative. This is equivalent to

• A. work done by electrostatic force in bringing the unit positive charge from infinity to the point $P$ is positive
• B. work done by the electrostatic force in bringing the unit positive charge from infinity to the point $P$ is negative
• C. Both (a) and (b)
• D. Neither (a) nor (b)

Answer 1

Answer: (A)

Work done by the electrostatic force in bringing the unit positive charge from infinity to the point $P$ is positive.
