  • 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?

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?

Answers (1)

The dimensions of -

Force = [M^{1}L^{1}T^{-2}]

          =100 N               ..........(i)

Length = [L^{1}]

          = 10 m         ...........(ii)

Time  = [T^{1}]

         = 100 sec   ...........(iii)

Now let us substitute the values of eq. (ii) & (iii) in eq. (i)

We get,

M\times10\times100^{-2}=100

\frac{10M}{10000}=100

Thus, M=10^{5}kg, L=10^{1}m,F=10^{2}N \; and \; T=10^{2}seconds
