Find the gravitational force between two stones, each of mass 2 ~kg and separated by a distance 1 ~m in vacuum.

Options

  1. A0
  2. B6.675 10⁻⁵ ~N
  3. C6.675 10⁻¹¹ ~N
  4. D2.67 10⁻¹⁰ ~N

Correct answer

D. 2.67 10⁻¹⁰ ~N

Step-by-step solution

Given, masses of two stones, m=2 ~kg Separation, d=1 ~m Since, gravitational force, F= G m^2 d^2 where, G=6.67 10¹¹ ~N - m ^2 ~kg ⁻² F= 6.67 10⁻¹¹ 2^2 1^2 =2.67 10⁻¹⁰ ~N
