Question

In a new system of units 1 unit mass is `4 kg`, 1 unit length is 3 meters and 1 unit time is 2 seconds. Now find x such that 1unit force in new system becomes x newton.
A. 3
B. 4
C. 8
D. 6

Answer 1

Correct Answer - A
`[F] = MLT^(-2)`
In new system
`1 "unit force" = ((1 "unit mass") (1 "unit length"))/((1 "unit time")^(2))`
`= ((4 kg)(3m))/((2 sec)^(2)) = 3 N`
