Change in acceleration due to gravity is same upto a height h from each other the earth surface and below depth x , then relation between x and h is ( h and x R_e )

Options

  1. Ax=h
  2. Bx=2 h
  3. Cx= h 2
  4. Dx=h^2

Correct answer

B. x=2 h

Step-by-step solution

Variation in g at a height h from the earth surface g^ =g (1- 2 h R_e ) Variation in g at a depth x below the earth surface g^ =g (1- x R_b ) But variations are same g (1- 2 h R_ )=g (1- x R_ ) x=2 h
