Question

The force of gravity on Planet B is 3.4 m/sec2. A box weighs 34 N on Earth. What is the mass of the box?

a)3.47 kg
b)333.2 kg
c)115.6 kg
d)10 kg

Answer 1

The answer will be 3.47....Option "a".

Answer 2

Answer:

The correct answer is option a.

Explanation:

Weight of an object is the force acting on an object by virtue of its mass.

Weight of box on earth , W= 34 N

Mass of the box  = m

The force of gravity on Planet earth = $g=9.8 m/s^2$

W = mg...[1]

$m=\frac{W}{g}=\frac{34 N}{9.8 m/s^2}=3.47 kg$

3.47 kilo gram is the mass of the box
