Question

Two large boulders are 8.5 m apart.one boulder has a mass of 3600 kg and the other rock has a mss of 2850 kg find the gravitational force betweeen them

Answer 1

`9.47 * 10^(-6)\; \text{N}`.

Step-by-step explanation

Constant of universal gravitation:

`G = 6.67 * 10^(-11) \;\text{m}^(3) \cdot \text{kg}^(-1) \cdot \text{s}^(-2)`.

Apply Newton's law of universal gravitation:

`F = (G \cdot m_1 \cdot m_2)/(r^(2)) =(6.67 * 10^(-11)* 3600 * 2850)/(8.5^(2)) = 9.47 * 10^(-6) \;\text{N}`.
