Q1. Electrostatic field lines do not form closed loops. If they closed loops then the work done in moving acharge along a closed will not be zero. From the above two statements can you guess nature of electrostatic force?
Answer
Ans.
Electrostatic field lines do not form closed loops if they closed loops then the work done in moving a charge along a closed will not be zero. These two statements indicate that the electric force is conservative.
