Question

What is the mass of an object whose weight is 49 N? Take g = 9.8 $m{s}^{-2}$

• A. 3 kg
• B. 4 kg
• C. 5 kg
• D. 6 kg

Answer 1

The correct option is C

5 kg

Given, weight(W) = 49 N and g = 9.8 $m{s}^{-2}$

Now we know, weight = $\text{mass of body}\times g$

49 = $\text{mass of body}\times 9.8$

mass of body = $\frac{49}{9.8}$ = 5 kg
