Answer 2

The true statement is : Electrostatic force is a conservative force.

To properly understand this answer, we have to analyse each of the given options.

Analysis of the given options :

• In case of electrostatic force, the work done is independent of path, it only depends on the final and initial positions of the charge. This path independent nature makes electrostatic force a conservative force. Thus, the option a becomes true, and the opposite statement (ie. electrostatic force is non conservative) mentioned in option c becomes false.
• In option b there's a wrong definition of the potential at a point. Because, potential at a point means the work done per unit charge in bringing a charge from infinity to a point. Thus, option b is false.
• And, potential is the ratio of charge and work. So, the statement mentioned in option d is also false.

Hence, the true statement is, electrostatic force is a conservative force.
