Question

A 10 kg ball is falling on the planet Mars. Mars has an acceleration due to gravity of about 4 m/s/s. What is the force of gravity (or weight) of the ball on Mars?

A.6N
B.40N
C.0.4N
D.14N

Answer 1

The force of gravity = 40 N

Step-by-step explanation:

Given that,

The mass of a ball, m = 10 kg

The acceleration due to gravity on the surface of Mars, a = 4 m/s²

We need to find the force of gravity of the ball on Mars. The force of gravity on an object is given by :

F = mg

Substitute all the values,

F = 10 kg × 4 m/s²

F = 40 N

Hence, the correct option is (B).
