Question

Find the CGS unit of the following derived quantities : Give the relation of these CGS units with respect to their SI units.
Momentum

Answer 1

Given, momentum $=$ mass $\times$ velocity,
C.G.S. unit of momentum $=$ ?

$\therefore$ C.G.S. unit of velocity $=gram\times cm{s}^{-2}=g.cm{s}^{-2}$

$\therefore$ C.G.S. unit of momentum $=gcm{s}^{-1}$

$1gcm{s}^{-1}={10}^{-5}kgm{s}^{-2}$
