Statement-I: Intensity of gravitational field inside a shell is not zero. Statement-II: Planets describe equal area around the sun in equal intervals of time.

Options

  1. ABoth Statement-I and Statement-II are correct.
  2. BBoth Statement-I and Statement-II are incorrect.
  3. CStatement-I is correct & Statement-II is incorrect.
  4. DStatement-I is incorrect & Statement-II is correct.

Correct answer

D. Statement-I is incorrect & Statement-II is correct.

Step-by-step solution

- Inside a uniform spherical shell, the gravitational field is zero everywhere (shell theorem), so saying it is "not zero" is wrong. - Planets sweep out equal areas in equal times around the Sun (Kepler's 2nd law), true due to conservation of angular momentum under a central force.
