Two small equal spheres carrying unlike and unequal charges are placed 8 cm apart and attack each othwer with a force of 4xx10^(-5) N. After they have been connected for a moment by a thin conducting wire, they repel each other with a force of 2xx10^(-5) N. Calculate their original charges.

(a) Two identical spheres having positive charges are placed 3 m apart repel each other with a force 8 xx 10^(-3) N . Now charges are connected by a metallic wire, they begin to repel each other with a force of 9 xx 10^(-3) N . Find initial charges on the spheres. (b) Two identical spheres having charges of opposite sign are placed 3 m apart attract other with a force 2.4 xx 10^(-3) N . Now spheres are touched and then placed at original separation repel with a force 10^(-3) N . Find initial charges on the spheres.
