Question

Calculate the magnitude of the gravitational force exerted by the Moon on a 79 kg human standing on the surface of the Moon. (The mass of the Moon is 7.4 × 1022 kg and its radius is 1.7 × 106 m.)

Answer 1

Answer:

F= 134.92 N

Explanation:

Given that

The mass of the moon ,M = 7.4 x 10²² kg

The mass of the man ,m = 79 kg

The radius ,R= 1.7 x 10⁶ m

The force exerted by moon is given as

$F=G\dfrac{Mm}{R^2}$

Now by putting the values in the above equation we get

$F=6.67\times 10^{-11}\times \dfrac{79\times 7.4\times 10^{22}}{(1.7\times 10^6)^2}\ N\\F=134.92 N$

Therefore the force will be 134.92 N.

F= 134.92 N
