If M is the mass of the earth and R its radius, the ratio of the gravitational acceleration and the gravitational constant is

Options

  1. AR² M
  2. BM R²
  3. CM R²
  4. DM R

Correct answer

B. M R²

Step-by-step solution

The gravitational acceleration on earth is given by aligned g &= F m = G M m R² m = G M R² g G &= M R² aligned
