Question

Q 10 New system of units is so chosen that the unit of mass equals A kg,the unit of lengths is b meter and unit of
time is c sec .How much will 5 joules measure in this new system.
​

Answer 1

unit of mass  =  α   kg

unit of length =  β   meters

unit of time   =  γ   seconds

=>  1 unit of new Energy unit = [ M L² T⁻² ]

      = α β² / γ²     kg m² / sec²

      = α β² / γ²  Joules

SO 5 Joules  will measure  :    5 γ² / (αβ²)    units
