Periodic time of a satellite revolving above the earth's surface at a height equal to radius of the earth ' R ' is [ g= acceleration due to gravity]

Options

  1. A2 2 R g
  2. B4 2 R g
  3. C2 R g
  4. D8 R g

Correct answer

B. 4 2 R g

Step-by-step solution

T =2 ( R + h )^3 gR ^2 =2 (2 R )^3 gR ^2 .( h = R )=4 2 R g
