Answer:
The force of gravity = 40 N
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).
