Question

What gravitational force does the moon produce

Answer 1

Answer:

$F = 1.94 \times 10^{20} N$

Explanation:

Mass of earth ; $M = 5.973 \times 10^{24} kg$

Mass of moon ; $m = 7.34 \times 10^{22}kg$

distance between them is ;$d = 3.88 \times 10^{8}m$

Gravitational constant is given by

$G = 6.67 \times 10^{-11} m^{3}kg^{-1}s^{-2}$

So , the gravitational force between them is

$F = \frac{GMm}{d^{2}}$

Insert the values

$F = \frac{6.67 \times 10^{-11} \times 5.973 \times 10^{24} \times 7.34 \times 10^{22}}{(3.88 \times 10^{8})^{2}} N$

So,

$F = 1.94 \times 10^{20} N$

Thus , the force between earth and moon is $F = 1.94 \times 10^{20} N$
