Two identical conducting balls A and B have positive charges q 1 and q 2 respectively. But . The balls are brought together so that they touch each other and then kept in their original positions. The force between them is
Text Solution
Verified by ExpertsThe correct answer is:
B
According to Coulomb's law, the force of repulsion between them is
When the charged spheres A and B are brought in contact, each sphere will attain equal
charge
Now, the force of repulsion between them at the same distance r is
As
