Question

In C.G.S system the magnitude of the force is $100$ dyne. In another system where the fundamental physical quantities are kilogram, metre, and minute, the magnitude of force is:

• A. $0.036$
• B. $0.36$
• C. $3.6$
• D. $36$

Answer 1

The correct option is C $3.6$

$Force=M^1{L}^1{T}^{-2}=100\frac{gmcm}{s^2}$

$=100\times \frac{\left({10}^{-3}\right)kg\times \left({10}^{-2}\right)m}{\left(\frac{1}{60}{)}^2\right(min{)}^2}$

$=3.6\frac{kgm}{(min{)}^2}$
