Question

If mass of a body is 30 kg, its weight of this body on moon will be (take g on Earth= 10 m/s2): *

1 point

(a) 4 N

(b) 5 N

(c) 50 N

(d) 8 N

​

Answer 1

Option C is right.

• Mass of body, m = 30 kg

• Acceleration due to gravity on earth, g = 10 m/s²

We know that,

Acceleration due to gravity on moon is one sixth of the acceleration due to gravity on earth.

Let g' be the acceleration due to gravity on moon.

g' = g/6

Weight is defined as the force of gravity acting on an object.

Force = ma

Weight on moon = mass × acceleration due to gravity on moon

$w = mg' \\ \\ w = m \times \frac{g}{6} \\ \\ = 30 \times \frac{10}{6} \\ \\ = \frac{30}{6} \times 10 \\ \\ = 5 \times 10 \\ \\ w = 50 \: newton$

The weight of the body on moon is 50 N.
