Question

3. There are two solid dielectric sphere of radius 'R' having
uniformly distributed charge. The Coulombian force F acting between them will depend on the sphere of
radius 'R':
(A) F proportional to R^-1
(B) F proportional to 1/R^-3
(C) F proportional to R^4
.(D) F proportional to R^-2​

Answer 1

Answer:

Explanation:

There are two types of observed electric charge, which we designate as positive ... F r. (2.2.1) where is the Coulomb constant, and e k. ˆ. /r. = r r is a unit vector ... That is, the small sphere experiences a repulsive force away from the van de ... devised to be proportional to the magnitude of the electric field in a given region.
