Question

How to calculate the mass to find if the object like 98N

Answer 1

Answer:

F = m*g

98 = m × 9.8

m = 98/9.8

= 10 kg

Answer 2

Weight of the object is 98 N under the action of Gravity.

We need to find the mass of the object.

So,

From Newton's second law of motion we can say that :-

Force = Mass * Acceleration

Force = Mass * Gravity

So,

Mass*9.8 = 98

Mass = 98/9.8 = 10 kg

Thus, mass of the object is 10 kg.

Now

Weight is a force acting towards the earth. Thus the SI unit of Weight will be Newton or kg m/sec²

While mass has a SI unit equivalent to kg and other related quantities.

Hence,

Mass and Weight are different quantities.
