If two identical spherical bodies of same material and dimensions are kept in contact, the gravitational force between them is proportional to R ^ X , where x is non zero integer [Given : R is radius of each spherical body]

Options

  1. A-4
  2. B4
  3. C2
  4. D-2

Correct answer

B. 4

Step-by-step solution

aligned F & = G m m (2 R)^2 = G ( 4 3 R^3 )^2 4 R^2 & = 4 9 ^2 ^2 R^4 F & R^4 aligned
