Question

A 4.0 kg object will have a weight of approximately 14.8 N on Mars. What is the gravitational field strength on Mars?

40 N/kg
3.7 N/kg
1.48 N/kg
0.27 N/kg

Answer 1

field strength =force/unit mass
= 14.8N/ 4kg = 3.7N/kg

Answer 2

The gravitational field strength on Mars is 3.7 N/kg.

Step-by-step explanation:

Given that,

Mass of the object, m = 4 kg

Weight of the object on Mars, F = W = 14.8 N

We need to find the gravitational field strength on Mars. It is given by gravitational force per unit mass of an object. Mathematically, it is given by

`G=(F)/(m)`

`G=(14.8\ N)/(4\ kg)`

G = 3.7 N/kg

So, the gravitational field strength on Mars is 3.7 N/kg. Hence, this is the required solution.
