Question
Calculate the gravitational force which Sun exerts on Jupiter.
✓

Answer

Given: G = 6.67 × 10-11Nm2/ kg2
MJ = 1.9 × 1027kg
Ms = 1.99 × 1030kg
Mean distance = 7.8 × 10+11m
$\text{F}_\text{g}=\frac{\text{GM}_{\text{S}}\text{M}_\text{J}}{\text{r}^2}$
$=\frac{6.67\times10^{-11}\times1.99\times10^{30}\times1.9\times10^{27}}{(7.8\times10^{11})^2}$
$=4.145\times10^{23}\text{N}$
