Question

Calculate the gravitational force between 2 stars having mass $10^{25} k g$ and $5 \times 10^{30} k g$ respectively. Distance between them is $2 \times 10^{10} m$ .

Open in App

Solution

According to universal law of gravitation,
$F = G \frac{M_{1} M_{2}}{R^{2}}$
where:
F = gravitational force
G = gravitational constant
$M_{1}$ =mass of star 1
$M_{2}$ =mass of star 2
R=distance from star 1 to star 2
$F = 6.673 \times 10^{- 11} \times \frac{10^{25} k g \times 5 \times 10^{30} k g}{(2 \times 10^{10} m)^{2}} = 8.34125 \times 10^{24} N$ .
