Question

1. Two charged particles exert a 20 N force on each other. What force will they exert on each other if the distance between them is reduced to one-half its original distance?

Answer #1

**Force between the two
charged particles given by Coulomb's law.**

**F is inversely proportional
to square of distance between them. **

**if we reduce the distance
to the half of original distance then the force become 4
times.**

**if Original force exerted
between them is 20N then new force will be 4 times of 20N =
80N.**

Two
small charged objects attract each other with a force F when
separated by a distance d/2. If the charge on each object is
reduced to one-fourth of its original value and the distance
between them is reduced to d/4 the force in the second case is
related the force in the first case by :
