Two identical conducting balls A and B have charges- Q and + 3Q respectively. They are brought in contact with each other and then separated by a distance d part. Find the nature of the Coulomb force between them.

Two identical conducting balls having positive charges q_1 and q_2 are separated by a center to center distance r. If they are made to touch each other and then separated to the same distance, the force between them will be.

Two indentical conducting balls A and B have positive charges q_1 and q_2 respectively. But q_1neq_2 . The balls are brought together so that they touch each other and then kept in their original positions. The force between them is

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.

Two identical conducting balls having positive charges q_(1) and q_(2) are separated by a center to center distance r. If any are made to touch each other and then separated to the same distance the force between them will be ……… .
