Question

electric line of force do not form closed curve why urgent​

Answer 1

Answer:

The test charge does not tend to return to its starting point so the field line doesn't form a closed loop. ... If the electric field lines form a closed loop, these lines must originate and terminate on the same charge which is not possible because electric field lines always move from positive to negative.

Answer 2

Explanation:

If the electric field lines form a closed loop, these lines must originate and terminate on the same charge which is not possible because electric field lines always move from positive to negative. ... Therefore, we say electrostatic field lines never form closed loops
