Charges of 5μC each are placed at the corners of an equilateral triangle of side 10 cm. Then the force on each charge is:-
Three charges each equal to 10−9C are placed at the corners of equilateral triangle of side 1 m. The force on one of the charges is:
Two charges of +200μC and −200μC are placed at the corners B and C of an equilateral triangle ABC of side 0.1m. The force on a charge of 5μC placed at A is :
