Question

An object has mass 4 Kg. What is its weight on earth in (a) Newton (b) Dyne?

Answer 1

a)Newton =40
b)Dyne=3922660

Answer 2

In this question we need a series of conversion.

We need a conversion formula from Kilograms to Newtons and then from Newtons to Dyne.

The conversions are as follows:

a) 1 kg = 10 N

b) 1 N = 100000 dyn e

We begin with the first conversion to convert the kgs to Newtons.

We do this as follows :

= 4 × 10 = 40 N

We apply the second conversion given that we have the mass in Newtons.

Applying the second conversion we have :

40 × 100000 = 4000000 dyne
