1.	The curve represents the distribution of potential along the staight line joining the two charges `Q_1 and Q_2` (separated by a distance r) then which of the following statements are correct? 1. `\|Q_1\|gt\|Q_2\|` 2. `Q_1` is positive in nature 3. A and B are equilibrium points 4. C is a point of unstabkle equilibriumA. 1 and 2B. 1,2,and 3C. 1,2 and 4D. 1,2,3 and 4
Answer» Correct Answer - A Over `Q_1` potential is `+alpha`. Hence `Q_1` is positive. `V_A=0` and A point is nearer to `Q_2`. Therefore `Q_2` should be negative and `\|Q_1\|gt\|Q_2\|`. At A and B, potential is zero, not the force. Equilibrium at C will depend on the nature of charge with is kept at C.
