Question 32

Scientists design a robot to explore other planets and moons.

The robot has a mass of 40 kg.

The Table shows the gravitational field strength at the surface of some places in the Solar System.

Table

Place	Gravitational field strength in $N/kg\text{N/kg}$
Earth	10
Moon	1.6
Mars
Jupiter	25

Calculate the weight of the robot on the Moon.

[2]

The weight of the robot on Mars is 148 N.
