Three charges +Q1,Q2, and q are placed on a straight line such that q is somewhere in equilibrium,what should be the magnitude and sign of charge q ?
Three charges +Q1,Q2 and q are placed on a straight line such that q some where in between +Q1 And +Q2. If this system of charges is in equilibrium, what should be the magnitude and sign of charge q.
Consider the situation shown in figure. What are the signs of q1 and q2?
