Question

draw a graph to represent the variation of electric field intensity with the distance r from the center of a uniformly charged solid sphere?

Answer 1

Answer:

The variation of the electric field can be drawn as below:

r is the distance from the centre of the sphere and R is the radius of the sphere.

r<R

E=kar/R^3

It is a straight line passing through origin

With maxima at r=R

E=kq/R^2

For r>R,it becomes a parabola.

E=kq/r^2
