Question

Three equal and similar charges are placed at the three vertices of an equilateral triangle of

side 20 cm. Find the force on any charge due to the other two if the magnitude of each
charge is 2.4 μC

Answer 1

According to Coulomb's law F=kQq/r ^ 2, the Coulombic force between charges with the same positive and negative electrodes is the repulsive force. Based on the vector synthesis of force, it can be concluded that F=√ 3 (kQq/r ^ 2)=√ 3k (2.4 * 10 ^ -3) ^ 2/(0.2 ^ 2) N=k1.44 √ 3 * 10 ^ -4N
