Question

Calculate the force of gravitation between two bodies of mass 100 kg each and separated by a distance of 1 m.
[G = 6.67 × 10–11 Nm² kg⁻²]

Answer 1

For the solution we can use the formula F = GM1M2/r2

Answer 2

Force of gravitation = 6.67 * 10^-7 Newtons

Explanation:

Given G = 6.67 * 10^-11

m1 = m2 = 100 kg

Distance = 1 m

Force of gravitation between two bodies can be calculated from the formula, F = Gm1m2 / r^2 where F is the force of gravitation, G is gravitational constant, m is mass of the bodies and r is the distance separating them.

So force of gravitation = G * m1 * m2 / r^2

= 6.67 * 10^-11 * 100 * 100 / 1*1

= 6.67 * 10^-7 N
