Question

two charged spheres with charge 2q and -4q separated by a distance d experience a force of F they are allowed to touch.Now the distance to be maintained between them to have same magnitude of force is​

Answer 1

Answer:

Then we can use Coulomb's law to calculate the force as it deals with charge on two particles separated by a distance and force. Complete answer: ... Therefore, after separation each sphere will have the charge of 1q. Therefore, now the force will be repulsive as the charges are of the same polarity.
