Question

Find the force between two objects
of
2 kg and 3 kg when they
100 meter apart.
​

Answer 1

Answer:

4.002 × 10^(-14) newtons

Explanation:

From Newton's Universal Law of Gravitation,

F = (m1 × m2 × G) ÷ r^2

F = [2 kg × 3 kg × 6.67 × 10^(-11) N.m^2/kg^2] ÷ (100 m)^2

F = 4.002 × 10^(-14) N

Answer 2

Given :

• Mass of object 1 ( m1) = 2 kg
• Mass of object 2 (m2) = 3 kg
• Distance b/w them = 100 m

To Find :

• Force between them

Solution :

$⠀⠀⠀⠀⠀⠀⠀\bold{\boxed{\sf{\red{F\:=\: \dfrac{Gm_1 m_2}{(r)²}}}}}$

$⠀⠀⠀⠀⠀\leadsto \sf F\:=\: \dfrac{6.67 \times {10}^{-11} \times 2 \times 3}{(100)²}$

$⠀⠀⠀⠀⠀\leadsto \sf F\:=\: \dfrac{40.02 \times {10}^{-11}}{10000}$

$⠀⠀⠀⠀⠀\leadsto \sf F\:=\:40.02 \times {10}^{-11\:-4}$

$⠀⠀⠀⠀⠀\leadsto \sf Force\:=\: 40.02 \times {10}^{-15} \:N$

• Force b/w the objects = $\sf 4.002 \times {10}^{-14}\:N$
