Question

A ball carrying a positive charge hangs from a silk thread. If we keep a positive test charge q₀ at a point and measure the force F on the test charge, then it can be said that the electric field strength E at the point will be

Answer 1

Correct Answer is option (A)

As the positive charge q₀ is brought near the ball due to the mutual repulsion the distance of ball from the charge increases hence the predicted field E is greater than the measured field F/q₀(F decreases with increasing distance).
