Question

calculate the gravitational force of attraction between two bodies of mass 40kg and 80kg separated by a distance of 15m.

Answer 1

Gravitational Force is given by F= GMm/R^2

F=6.67x10^-11 x 40 x 80 / (15x15)

= 6.67x10^-11 x 14.22 N

= 9x10^-10 N

Answer 2

Hey there!

Answer:

$\boxed{F = 9.5 \times 10^{-10} \ N}$

Step-by-step explanation:

Given,

Masses of bodies = 40 kg and 80 kg

Distance between them = 15 m

G = 6.7 * 10⁻¹¹ N m² kg⁻²

We know,

$\sf F = \dfrac{Gm_1m_2}{r^2}\\\\F =\dfrac{6.7 \times 10^{11} \times 40 \times 80}{15 \times 15} \\\\\boxed{F = 9.5 \times 10^{-10} \ N}$

Hope it Helps You!
