Two metallic spheres carry equal charges. The distance between the spheres cannot be considered large in comparison with the diameters of the spheres. In which case, will the force of interaction between the spheres be greater ?

Question

experimentx · Answer

the force of interaction depends on the product of charges and distance between them.

to be exact: 
the force of interaction between two charges will be directly proportional to product of charges between the and inversely proportional to the square of distance between them. It's called column law. Please refer wikipedia,
