Question

Calculate the force of gravitation between two objects of masses 80 kg and 1200 kgkept at a distance of 10 m from each other

Answer 1

Mass of object ($m_1$) = 80 kg

Mass of object ($m_2$) = 1200 kg

Distance between the masses (r) = 10 m

Values of universal gravitation constant (G) = $6.67 \times 10^-^1^1 Nkg^-^2m^2$

Force between the masses = $\frac{G m_1 m_2}{r^2}$

$F = \frac{6.67 \times 10^-^1^1 \times 80 \times 1200}{10^2}$

$F = 6.4 \times 10^-^8 N$

Hence, the gravitational force between the two masses is: $F = 6.4 \times 10^-^8 N$
