A satellite is moving round the earth in a circular orbit. The following statements are given :- (i) It is moving with a constant velocity. (ii) It has no acceleration. (iii) It's angular momentum w.r.t. centre of the earth remains conserved. (iv) Its distance from center must be equal to ( 2 ) times of earth's radius. The correct option is :-

Options

  1. Ai & ii are true
  2. Bi, iii & iv are true
  3. Conly iii is true
  4. Di & iv are true

Correct answer

C. only iii is true

Step-by-step solution

Satellite in circular orbit has constant speed, but not constant velocity and it will have centripetal acceleration.
