Question

The given graph shows variation (with distancer from centre) of :

• A. Potential of a uniformly charged sphere
• B. Potential of a uniformly charged spherical shell
• C. Electric field of uniformly charged spherical shell
• D. Electric field of uniformly charged sphere

Answer 1

The correct option is B Potential of a uniformly charged spherical shell

According to given graph,

Y- component is not changing up to distance $r_0$

After $r_0$, Y- component is decreasing uniformly

For uniformly charge sphere potential is not constant inside the sphere. But in case of shell Potential is constant Inside the sphere. And potential outse the sphere decreases Uniformly.

Electric field is zero in both case either shell or solid sphere.

Hence option B.
