The height above the earth's surface at which the acceleration due to gravity becomes ( 1 n ) times the value at the surface is ( R= radius of earth)

Options

  1. AR n
  2. BR n
  3. C( n +1) R
  4. D( n -1) R

Correct answer

D. ( n -1) R

Step-by-step solution

array ll & Given: g ^ g = 1 n & 1 n = R ^2 ( R + h )^2 R R + h = 1 n & n R = R + h & R ( n -1)= h array
