Three point charges are placed at the co...

Three point charges are placed at the corner of an equilateral triangle. Assuming only electrostatic forces are acting.

A

The system can never be in equilibrium

B

The system will be in equilibrium if the charges rotate about the centre of the triangle

C

The system will be in equilibrium if the charges have different magnitudes and different signs

D

The system will be in equilibrium if the charges have the same magnitudes but different signs

Text Solution

Verified by Experts

The correct Answer is:
A

Since, `F_C ne 0 , F_B ne 0 , F_A ne 0`
and `vecF_A + vecF_B +vecF_C ne 0`
Hence, system can never be in equilibrium.
