  • 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
