Question

Two 1 Kg masses are 1 cm apart. What is the force felt by one of these masses due to the other mass?

Answer 1

Answer:

Gravitational force between two 1 kg mass is given as

$F = 6.67 \times 10^{-7} N$

Explanation:

Gravitational force of attraction between two masses is given by the formula

$F = \frac{Gm_1m_2}{r^2}$

now we know that

$m_1 = m_2 = 1 kg$

r = 1 cm

so we will have

$F = \frac{(6.67 \times 10^{-11})(1)(1)}{0.01^2}$

$F = 6.67 \times 10^{-7} N$
