Two positive charges which are 0.1m apart repel each other with a force of 18N. If the sum of the charges be `9 muC`, calculate their separate values.

Two positive charges separated by a distance 2m repel each other with a force of 0.36N. If the combined charge is 26muC , the charges are

Two positive charges separated by a distance 2m each other with a force of 0.36N. If the combined charge is 26muC , the charges are

Two point charges of +3muC and +4muC repel each other with a force of 10 N. If each is given an additional charge of -6muC , the new force is

Two point charges of +3muC and +4muC repel each other with a force of 10 N. If each is given an additional charge of -6muC , the new force is

Two point charges of +2 muC and + 6 muC repel each other with a force of 12 N. If each is given additional charge of -4 muC , what will be the new force ?

(a) Two identical sphereshaving 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 signare 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.
