Two insulated identically sized charged copper spheres A and B have their centers separated by a distance 50 cm. Charges on each sphere is q=6.5× 10^(-7) C. A third sphere of the same size but uncharged is brought in contact with the first, then brought in contact with the second, and finally removed from both. What is the new force of repulsion between A and B?

The sphere A and B have identical sizes. A third sphere of the same size but uncharged is brought in contact with the first, then brought in contact with the second and finally removed from both. What is the new force of repulsion between A and B?

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.

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 identical conducting spheres M and N has charge q_M and q_N respectively. A third identical neutral spehre P is brought in contact with M and then separated. Now, sphere P is brought in contact with N and then separated. Find out final charge on the spehre P.

A ball of charge q is plaed in a hollow conductive uncharged sphere. After this, the sphere is connected with earth for a short time and the ball is then removed from the sphere. The ball has not been brought into contact with the sphere. What will be the nature of the field and how wil it be located?

A ball of charge q is plaed in a hollow conductive uncharged sphere. After this, the sphere is connected with earth for a short time and the ball is then removed from the sphere. The ball has not been brought into contact with the sphere. What charge will the sphere have after these operations? Where and how will this charge the distributed?

Two small charged metal sphere A and B are situated in a vaccum. The distance between the centres of the spheres is 12.0 cm, as shown in the fig. The charge on each sphere may be assumed to be a point charge at the centre of the sphere. Point P is a movable point that lies on the line joining the centres of the sphere and is distance x fromt he centre of sphere A. The variation with distance x fo the electric field strength E at point P as shown in the figure. State the evidence provided by in the fig for the statement that the spheres are conductors, the charges on the spheres are either both positive or both negative.

Two identical plane metallic surfaces A and B are kept parallel to each other in air separated by a distance of 1.09 cm as shown in Fig. HQ 6. Surface A is given a positive Potential of 10 V and outer surface of B is earthed. What is the work done in moving a charge of 20 muC from point X to Y. Where X is situated on surface A?
