Potential Due To Hollow Conductiong, Solid Conducting, Hollow Non Conducting MCQ - Practice Questions with Answers

Electric Potential due to Hollow conducting, Hollow non-conducting, Solid conducting Sphere-

In the case of Hollow conducting, Hollow non-conducting, Solid conducting Spheres charges always resides on the surface of the sphere.

If the charge on a conducting sphere of radius R is Q. And we want to find V at point P at distance r from the center of the sphere.

• Outside the sphere (P lies outside the sphere. I.e r>R)

• Inside the sphere (P lies inside the sphere. I.e r<R )

            and it is given as 

• At the surface of Sphere (I.e at r=R)

• The graph between (E vs r)  and (V vs r) is given below

Electric Potential due to Uniformly charged Non conducting sphere-

Suppose charge Q is uniformly distributed in the volume of a non-conducting sphere of Radius R.

And we want to find V at point P at distance r from the center of the sphere.

• Outside the sphere (P lies outside the sphere. I.e r>R)

• Inside the sphere (P lies inside the sphere. I.e r<R )

• At the surface of Sphere (I.e at r=R)

Note - If P lies at the centre of the uniformly charged non-conducting sphere (I.e at r=0)

i.e         

• The graph between (E vs r)  and (V vs r) is given below
