1. The problem statement, all variables and given/known data
A negatively charged metallic ball is supported on an insulating stand.We wish to measure the electric field at a point P in the same horizontal level as that of the metallic ball.To do so,we put a positive charge q and measure F/q.The electric field at the point P is
a)=F/q
b)<F/q
c)>F/q

the answer given is <F/q...i cant understand how..


2. Relevant equations



3. The attempt at a solution
