Question

Two masses 500 kg and 200 kg are placed at a distance of 0.5 m apart. If the gravitational force between them is 25 × 10-6 N find the gravitational constant.

Answer 1

Explanation:

the formula of gravitational force is

F=G m1m2/r^2

G is the gravitational constant.

G=Fr^2/m1m2

Putting values

G=25×10^-6×0.5^2/(500)(200)

G=6.25×10^-11Nm2/kg2

Answer 2

Explanation:

The formula of gravitational force is

F = G m1m2/r^2

G is gravitational constant .

G = Fr^2/m1m2

Putting values

G = 25 × 10^ - 6 × 0.5^ 2 / (500) (200)

G = 6.25 × 10^ - 11Nm2/kg 2
