Question

Two objects of masses 20 kg and 40 kg are separated by a distance of 15 m. If G = 6.67 × 10^-11 Nm^2/kg^2, then calculate the gravitational force of attraction​

Answer 1

Answer- $F= 2.37 \times {10}^{-12} N$

Explanation:

Given-

$m_1 = 20kg$

$m_2 = 40kg$

$distance \ (d) = 15 cm$

Find-

$Force \ of \ gravitation \ F= \dfrac {Gm_1m_2}{{d}^{2}}$

$F = \dfrac{6.67 \times {10}^{-11} \times 20 \times 40}{{15}^{2}}$

$F= 2.37 \times {10}^{-12} N$
