A double star system consists of two stars A and B which have time period T_A and T_B . Radius R_A and R_B and mass M_A and M_B . Choose the correct option.

Options

  1. AIf T_A>T_B , then R_A>R_B
  2. BIf T_A>T_B , then M_A>M_B
  3. C( T_A T_B )^2= ( R_A R_B )^3
  4. DT_A=T_B

Correct answer

D. T_A=T_B

Step-by-step solution

In case of binary star system angular velocity and hence the time period of both the stars are equal.
