An insulating rod carries some net charge, and a copper sphere is neutral. The rod and the sphere do not touch. Can there be force of attration/repulsion between the two?

(a) Two insulated charged copper spheres A and B have their centers speparated by a distance of 50 cm. What is the mutal force of electrostatic repulsion if the charge on each is 6.5xx10^(-7) C ? The radill of A and B are negalible compared to the distance of separation. (b) What is the force of repulsion if each sphere is charged double the above amount, and the distance between them is halved ?

Two insulated charged copper spheres A and B have their centres separated by a distance of 50 cm. What is the mutual force of electrostatic repulsion if the charge on each is 6.5 xx 10^(-2)C? The radii of A and B are negligible compared to the distance of separation. b. What is the force of repulsion if each sphere is charged double the above amount and the distance between them is halved?

Two insulated charged copper spheres A and B have their centres separated by a distance of 50 cm. What is the mutual force of electrostatic repulsion if the charge on each is 6.5 xx 10^-7 C ? The radii of A and B are negligible compared to the distance of separation. What is the force of repulsion if each sphere is charged double the above amount, and the distance between them is halved?

Two sphere M and N, having charge q_(1) and q_(2) are kept at some distance from each other.q amount of charge is taken from the sphere M and transferred ot the sphere N. What is the new charge of the two spheres so that the force acting between them becomes maximum?

A uniformly charged sphere, made up of non-conducting material and carrying charge Q, is placed near a uniformly charged non-conducting rod, carrying charge q. The centre of the sphere lies on the perpendicular bisector of the rod as shown in the figure. Calculate the force exerted by the sphere on the rod.

Two indentical metallic spheres A and B, each carrying a charge q repel each other with a force F. A third metallic uncharged sphere C of the same size is made to touch the spheres A and B alternately and then removed away. What is the force of repulsion between A and B ?

Two insulated metal spheres of the same size are charged with -15 esu and +25 esu. The distance between their centres is 10 cm. What is the force acting between the two charges? If the two spheres are made to touch each other and then placed in their previous positions, what will be the force acting between them?
