For spherical symmetrical charge distribution, variation of...

For spherical symmetrical charge distribution, variation of electric potential with distance from centre is given in diagram. Given that: V=q4πε0R0 for \frac{q}{4 \pi \varepsilon_0 R_0} \text{ for }r \leq R_0 and V=q4πε0rV=\frac{q}{4 \pi \varepsilon_0 r} for r≥R0r \geq R_0 Then which option(s) are correct For spherical symmetrical charge distribution, variation of electric potential with distance from centre is given in

Options

  1. ATotal charge within 2R02 R_0 is qq
  2. BTotal electrostatic energy for r≤R0r \leq R_0 is zero
  3. CAt r=R0r=R_0 electric field is discontinuous
  4. DNone of these

Correct answer

D. None of these

Step-by-step solution

The given graph is of charged conducting sphere of radius R0R_0. The whole charge qq distributes on the surface of the sphere.
