If T_A and T_B are the time period of star A and star B, respectively, Then :ATATB=(rArB)32{{{T_A}} \over {{T_B}}} = {\left( {{{{r_A}} \over {{r_B}}}} \right)^{{3 \over 2}}}TBTA=(rBrA)23BTA=TB{T_A} = {T_B}TA=TBCTA>TB{T_A} > {T_B}TA>TB (if mA>mB{m_A} > {m_B}mA>mB)DTA>TB{T_A} > {T_B}TA>TB (if rA>rB{r_A} > {r_B}rA>rB)Check answerSkip
