Consider a neutral conducting sphere. A positive point charge is placed outside the sphere. The net charge on the sphere is then

Options

  1. Anegative and distributed uniformly over the surface of the sphere
  2. Bnegative and appears only at the point on the sphere closest to the point charge
  3. Cnegative and distributed non-uniformly over the entire surface of the sphere
  4. Dzero

Correct answer

D. zero

Step-by-step solution

Charge will be induced in the conducting sphere, but net charge on it will be zero. Option (d) is correct.
