In a particular system the units of length, mass and time are chose to be 10 cm, 10 g and 0.1 s respectively. The unit of force in this system will be equal to :-

A

0.1 N

B

1 N

C

10 N

D

100 N

Text Solution

Verified by Experts

The correct Answer is:
A
`because ` [ force] = `[MLT^(-2)]`
`therefore` Unit of force = `(10 g) (10 cm) (0.1 s)^(-2)`
`" "= (10xx 10^(-3) kg)(10 xx 10^(-2) m) (10^(-1)s)^(-2)`
`" "= 0.1 kgms^(-2)`
`" " = 0.1 N`
