Question

In a particular system the units of length, mass and time are chosen to be `10 cm, 10 g` and `0.1 s` respectively. The unit of force in this system will be equal to
A. `0.1N`
B. `1N`
C. `10N`
D. `100N`

Answer 1

Correct Answer - A
Force `F = [MLT^(-2)] = (10g) (10cm) (0.1s)^(-2)`
Changing these units into MKS system
`F = (10^(-2) kg) (10^(-1)m) (10^(-1)s)^(-2)`
`10^(-1) N = 0.1N`
