Answer 2

New gravitational force will become four times the original one that is 16 N

Explanation:

• Gravitational force is the force between any two bodies in the universe separated by some distance and is given as

            $F = \frac{G m_{1}m_{2} }{r^{2} }$

where m₁ = mass of one object

m₂ = mass of another object

r = distance between the objects

G = gravitational constant

F = forces between the objects

Given force is 4 N

$F = \frac{G m_{1}m_{2} }{r^{2} }$

=> $4= \frac{G m_{1}m_{2} }{r^{2} }$        ........................................(1)

when distance is reduced to half let the new force is F₁ and the distance is r₁

=>  r₁ = $\frac{r}{2}$                  ................................(2)

New force is given as

F₁ = $\frac{G m_{1}m_{2} }{r_{1} ^{2} }$

=> F₁ = $\frac{G m_{1}m_{2} }{(\frac{r}{2} )^{2} }$                ( from equation (2))

=> F₁ = 4 *$\frac{G m_{1}m_{2} }{r^{2} }$

=>  F₁ = 4 F         ( from equation (1))

=>  F₁ = 4 * 4

=>  F₁  = 16 N
