Question

The mass of the body is 20 kg. If pull of gravity on mass 1 kg is 10N then find the weight of the child in a) kgf b) Newton​

Answer 1

Answer:

a) 4000 kgf  b) 4000N

Explanation:

force acting on 1 kg body is 10N

force acting on 20 kg body is (10*20)N = 200N

weight = mass * gravity

weight = 20kg * 200N = 4000 kgf

1 kgf = 1N

so,

    4000N
