Electrostatic Potential and Capacitance

Two charged spherical conductors of radius R1R_1 and R2R_2 are connected by a wire. Then the ratio of surface charge densities of the spheres (σ1/σ2\sigma_1/\sigma_2) is:

  1. A.R1R2\dfrac{R_1}{R_2}
  2. B.R2R1\dfrac{R_2}{R_1}✓
  3. C.R1R2\sqrt{\dfrac{R_1}{R_2}}
  4. D.R12R22\dfrac{R_1^2}{R_2^2}

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
