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?
A
103 kg
B
104 kg
C
105 kg
D
106 kg
Answer
105 kg
Explanation
Solution
Here, F = 100 N,L = 10 m, T = 100s
Dimensional formula of force is [MLT−2].
∴M=LT−2F=(10m)(100s)−2100N=105kg
