If the fundamental units of length, mass and time are doubled, the unit of force will

Options

A. doubled
B. tripled
C. quadrupled
D. eight times the original value

Answer

C

Explanation

When unit of mass, length ane time are doubled, then
`(J')/(J)=(kg-m^(2)//S)/(kg-m^(2)//S)(2kgm^(2)//S)/(2kg-m^(2)//S)`
`J'=4J=4`
the unit of angular momentum is quadrupled.
