Question

A backpack weights 8.2 newtons and has a mass of 5 kg on the moon. What is the strength of gravity on the moon?

Answer 1

Answer:

given 8.2 Newtons and as mass of 5 kg on the moon

to find centre of gravity on the moon

=8.2*5=42.5

Answer 2

The strength of gravity on the moon is 1.64m/s².

Given:

A backpack weighs 8.2 newtons and has a mass of 5 kg on the moon.

To Find:

The strength of gravity on the moon.

Solution:

To find the strength of gravity on the moon, we will follow the following steps:

As we know,

Force on the surface of the planet is calculated by the product of mass and acceleration due to gravity.

Force = mass × acceleration due to gravity

Now,

According to the question:

Force = 8.2N

Mass = 5kg

Now,

In putting values we get,

$acceleration = \frac{force}{mass} = \frac{8.2}{5} = 1.64m {s}^{ - 2}$

Henceforth, the strength of gravity on the moon is 1.64m/s².
