Question

Two identical conducting balls having

positive charges q1 and q2 are

separated by a distance r. If they are

made to touch each other and then

separated to the same distance, the​

Answer 1

Answer:

If they are made to touch each other, the electrostatic conduction will occur. As a result the total charge will get distributed equally on both the balls because both the balls are identical in nature.

Initially, F∝q

Now after making contact, charge on each ball will become Q

From above we can say that F
