In a system of units , the unit of force is 100N, unit of length is 10m and the unit of times is 100s. What is the unit of mass in this 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

What is the unit of atomic mass?

If the unit of force is 2N, that of length is 4m and that of velocity is 6ms^(-1) , the unit of mass is

The unit of speed in S.I system is

The density of a material in C.G.S. system is 8g/ cm^3 . In a system of units in which unit of length is 5 cm and unit of mass is 20g. What is the density of the material?

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.
