Find the gravitational force experienced by an object of 20 kg which is 200 m away from an object of 2 tons.

The equation for universal gravitation is given as: 
$\mathrm{F} = \frac{{\mathrm{GM}}_1{\mathrm{M}}_2}{{\mathrm{R}}^2}$

Here, G is the gravitational constant;  M₁ and  M₂ are the masses of the objects; R is a separation between the objects.

G = 6.67 X 10^-11 Nm²/kg²
M₁ = 20 kg
M₂ = 2 tons = 2000 kg
R = 200 m

Substituting the values, we get, 

$\mathrm{F} = \frac{6.67 \times {10}^{-11 }\times 20 \times 2000}{{200}^2}$

$\Rightarrow$F = 6.67 X 10^-11 N

Therefore, the object will experience a force of 6.67 X 10^-11 N
