Numerical Problem.

Find the mass of an object weighing 98 N

✓

Answer

weight = mass × gravity

We know tha, gravity = 9.8 ms-2

Given:-, weight = 98 N

$\begin{aligned} & \text { mass }=\frac{\text { weight }}{\text { mass }} \\ & =\frac{98}{8} \\ & =10 kg \end{aligned}$

Hence, mass of the object is 10 kg.
