The depth at which acceleration due to gravity becomes g n is [ R = radius of earth, g = acceleration due to gravity, n = integer]

Options

  1. AR(n-1) n
  2. B( n -1) nR
  3. CRn ( n -1)
  4. Dn R ( n -1)

Correct answer

A. R(n-1) n

Step-by-step solution

aligned & g ^ = g (1- d R ) & g n = g (1- d R ) & d = R ( n -1) n aligned
