Question

What is the weight in newtons of a 2.45 kg laptop computer? Assume g = 9.8 m/s2.

a)0.25 N
b)4.0 N
c)24 N
d)240 N

Answer 1

weight = mg = 9.8 x 2.35 = 24 N

Answer 2

We have: Weight = Mass × Gravity
Here, Mass = 2.45 Kg
Gravity = 9.8 m/s²

Substitute the values in to the formula:
Weight = 2.45 × 9.8 = 24.01

After rounding-off to the nearest tenth, it would be 24

So, Option C is your correct answer.

Hope this helps!
