Text solutionVerified

Gravitational force = Centripetal Force

\frac{G M _{p} M _{J}}{R _{p}^{2}} = \frac{M _{p} v _{p}^{2}}{R _{p}} ............... (1)

Also,

v_{p} = \frac{2 π R _{p}}{T _{p}} ............... (2)

Substituting (2) in (1),

M_{J} = \frac{4 π ^{2} R _{P}^{3}}{G T _{P}^{2}}

= 1.9 \times 1 0^{27} k g

M_{J} / M_{S} = \frac{1.9 \times 1 0 ^{27}}{2 \times 1 0 ^{30}} \approx 1 0^{- 3}
