Two objects of equal masses placed at certain distance from each other attracts each other with a force of F . If one-third mass of one object is transferred to the other object, then the new force will be

Options

  1. A2 9 F
  2. B16 9 F
  3. C8 9 F
  4. DF

Correct answer

C. 8 9 F

Step-by-step solution

The gravitational force between particles is given by, F = G m 1 m 2 r 2 ∵   F = G m 2 r 2 When one-third mass is transferred to other object m 1 = 2 m 3 ,   m 2 = 4 m 3 F 2 = 8 G m 2 9 r 2 ⇒ F 2 = 8 9 F
