Question

For spherical symmetrical charge distribution, variation of electric potential with distance from center is given in V=q4πϵ0R0forrR0 and V=q4πϵ0rforrR0 ,

Curve of potential → distance (r)

Curve of Potential → Distance (R)

Curve shows that from o to r = R0 potential becomes constant and from r > R0, it decays

Then which option are correct:

(1) Total charge within 2R 0 is q

(2) Total electrostatic energy for rR0 is non-zero.

(3) At r=R0 electric potential is discontinuous

(4) There will be no charge anywhere except at r<R0

Select the correct answers and mark it according to the following codes:
