Three point charges are placed at the corner of an equilateral triangle. Assuming only electrostatic forces are acting.
A. The system will be in equilibrium if the charges have the same magnitude but not all have same sign.
B. The system will be in equilibrium if the charges have different magnitudes and not all have the same sign
C. The system will be in equilibrium if the charges rotate about the centre of the triangle
D. The system can never be in equilibrium
