In a new system, if units for length mass and time are chosen to be 10 cm 10g and 0.1 s respectively, thennew unit of force in this system will be.....

Answer»

1
`0.1`
`0.01`
`0.001`

Solution :DIMENSIONAL formula of force `[F]=M^(1)L^(1)T^(-2)`
Now in new system
`F=(10g^(1)) (10 cm)^(1) (0.1 s)^(-2)`
`=(10^(-2) kg)^(1) (10^(-1) m)^(1) (10^(2)s^(-2))`
`=10^(-1) KGMS^(-1)`
`:.F=0.1` NEWTON
