Question

Two bodies of masses 1 kg each are situated 1 metre apart. Find the gravitational force between them.

Answer 1

Answer:

F = $\mathbf{6.67\times 10^{-11} N}$

Explanation:

In this question,

Two bodies of masses 1 k.g each are situated 1 meter apart

We need to find the gravitational force between them.

Gravitational force between two bodies is given by - $\frac{Gm_{1}m_{2}}{r^{2}}$

Where $m_{1}$ is the mass of the 1st body, $m_{2}$ is the mass of the 2nd body and r is the distance between both the bodies

Value of G = $6.67\times 10^{-11}$

Therefore, Putting the values we get

F = $\frac{6.67\times 10^{-11}\times 1\times 1}{1^{2}}$

F = $\frac{6.67\times 10^{-11}}{1}$

F = $\mathbf{6.67\times 10^{-11} N}$

So the force between the two body which is 1 meter apart is $6.67\times 10^{-11}$.
