Question

What is the magnitude of the force of gravity acting on a box that has a mass of 100 kilograms and is at sea level? A. 10.20 newtons B. 98 newtons C. 1,020 newtons D. 980 newtons

Answer 1

Answer: D. 980 newtons

Explanation:

The force of gravity that acts on a body is called weight $W$ and is defined as:

$W=m.g$  (1)

Where:

$m=100kg$ is the mass of the box

$g=9.8m/s^{2}$ is the gravity at sea level

Substituting these values in (1):

$W=(100kg)(9.8m/s^{2})$

$W=980N$

Answer 2

Answer:

d
