Question

Mass of a body is 5 kg. What is its weight?

Answer 1

1. Given data:

Mass of a body (m)= 5 kg

Acceleration due to gravity (g) = $9.8m/s^2$

Weight of the object (W) = ?

2. Calculating the weight of the object:

Applying the formula of weight,

$Weight=mass\times gravity$

$W=mg$

$$\begin{gathered} W=5kg\times 9.8m/s^2 \\ W=49N \end{gathered}$$

Hence , the weight of the body is 49 N.
