Q30 of 44 Page 9

If the unit of force is 100 N, unit of length is 10 m and unit of time is 100 s, what is the unit of mass in this system of units?

Given:


A unit of force = 100 N


A unit of length = 10 m


A unit of time = 100 s


The dimensional formula for Force is, F = [MLT-2].


Therefore mass, M = [FL-1T2].


Substituting the values force, length and time in the above relation we have



Therefore, in this system of units the unit of mass is 105 kg
