Question

A positively charged ball hangs from a long silk thread. Electric field at a certain point (at the same horizontal level of ball) due to the ball is E . If now put a positive test charge q 0 at this point and measure F q 0 , then E, > F q 0, F q 0, = F q 0, none of these

MARKS App · Accepted Answer

E = k Q r 2 .....(i) F = k Q q 0 r 1 2 ⇒ F q 0 = k Q r 1 2 ....(ii) As r 1 > r , so from equation (i) and (ii), we get E > F q 0
