If the unit of mass is alpha kg, the unit of length is beta metre and the unit of time is " gamma ' second, The magnitude of calorie in the new system is (1 Cal = 4.23)

1 calorie=4.2 J where IJ= 1 kg m^2s^-2 . Suppose we employ a system of units in which the unit of mass is alpha kg, the unit of length is beta m and the unit of time gamma s , show that a calorie has a magnitude 4.2alpha^-1beta^-2gamma^-2 in the new system.

If the unit of force is 1N, the unit of work done is 10 J and the unit of time is 1 second, the unit of mass is

The value of force in a certain system of measurement is 200 units. If unit of mass is doubled the unit of length is trebled, the unit of time is halved then the value of force in new system of units is x^(1//3) , then the value of x is

A force of 40N acts on a body. If the units of mass and length are doubled and the unit of time is tripled, then the force in the new system becomes
