Question

An object has mass 5kg. Its weight on the surface of the Earth is

a) 100 N b) 49 N c) 40 N d) 98 N​

Answer 1

Answer:

b)

Explanation:

So a 5kg object has a mass of 5kg. The weight you associate with it is only relevant on Earth (under its specific gravity) and in fact really the kilogram-force measurement which is measured in Newtons (5kg x 9.8m/s2 = 49.2N). ... Commonly, it means the object weighs 5kg.

Answer 2

Answer:

Mass = 5kg

g = 9.8m/s2

Weight = ?

So

W = M× g

W = 5 × 9.8

W = 49N
