A conducting sphere of radius R=20 ~cm is given a charge Q=16 C . What is E at centre?

Options

  1. A3.6 10^6 ~N / C
  2. B1.8 10^6 ~N / C
  3. CZero
  4. D0.9 10^6 ~N / C

Correct answer

C. Zero

Step-by-step solution

The value of E at the centre of sphere is zero. Since, the centre of sphere is placed with in the Gaussian surface. Hence E=0 .
