Question

Satellite A and B are revolving around the orbit of earth. The mass of A is 10 times of mass of B. The ratio of time period open parentheses T subscript A over T subscript B close parentheses is

  1. 10    
  2. 1    
  3. fraction numerator 1 over denominator 5 end fraction    
  4. fraction numerator 1 over denominator 10 end fraction    

The correct answer is: 1


    Time period of satellite
    T equals 2 pi square root of fraction numerator left parenthesis R subscript e end subscript plus h right parenthesis to the power of 2 end exponent over denominator g R subscript e end subscript superscript 2 end superscript end fraction end root
    W h e r e comma blank R subscript e end subscript equals R a d i u s blank o f blank e a r t h comma
    h equals H e i g h t blank f r o m blank e a r t h blank s u r f a c e blank.
    Time period not depend on mass. So, time period of both satellite will be equal.
