Answer 1

Answer:

40 Newton

Explanation:

as gravity apply 10N on 1 kg mass

Answer 2

Given,

The earth attracts a body of mass of 4 kg on its surface

To find,

Force

Solution,

The formula that gives the force of attraction is given below:

F = mg

where m is the body's mass (1 kg) and

g is the strength of the earth's gravitational field where the mass is.

We can estimate g to be around 10N/kg or possibly 9.8N/kg, although this varies depending on where you are.

The Force of Attraction F=1 x10 = 10N or 1 x 9.8 = 9.8N

The force for the body of mass 4 kg = 9.8N × 4 kg

The force = 39.2 kg

Hence, the force when the earth attracts a body of mass of 4 kg is 39.2 kg.
