Consider two satellites S 1 and S 2 with periods of revolution 1 hr and 8 hr respectively revolving around a planet in circular orbits. The ratio of angular velocity of satellite S 1 to the angular velocity of satellite S 2 is:

Options

  1. A8 : 1
  2. B2 : 1
  3. C1 : 4
  4. D1 : 8

Correct answer

A. 8 : 1

Step-by-step solution

T 1   T 2 = 1 8 2 π / ω 1 2 π / ω 2 = 1 8 ω 1 ω 2 = 8 1
