Question

A weight of the box on the Earth is 200 N. What will be its mass on the Moon? (2)

(g=10 m/s2)​

Answer 1

Answer:

Weight of box on the earth = 200N.

Also F = m × a.

or 200N = m × 10m/s^2.

Therefore m = 20kg.

Acceleration on moon = 1.63m/s^2.

WEIGHT ON MOON = (20 × 1.63) N = 32.6N

THEREFORE MASS ON THE MOON = 20KG AND WEIGHT = 32.6N.

Answer 2

weight = mass x gravity

⇒mass=weight/gravity

weight=200N=200kg; mass=200/10=20kg

(Neuton is a unit of force, so over here it means the force exerted by the box because of gravity)

mass in the moon=(mass on earth/9.81 m/s²) × 1.622 m/s²

=20/9.81×1.622

=3.37 kg
