      Question

      Two spherical conductors of radii 2 cm and 8 cm are

      connected. The ratio of charges on them at equilibrium is:
      A 1: 4 Correct Answer Incorrect Answer
      B 1: 1 Correct Answer Incorrect Answer
      C 2: 1 Correct Answer Incorrect Answer
      D 1: 2 Correct Answer Incorrect Answer

      Solution

      When connected, both spheres attain the same potential. Potential V = q/r β‡’ q₁/r₁ = qβ‚‚/rβ‚‚ β‡’ q₁/qβ‚‚ = r₁/rβ‚‚ So, q₁/qβ‚‚ = 2/8 = 1: 4.
