Question

State the unit of force. How is it related to the c.g.s unit of force? Explain.

Answer 1

Force:

S.I. unit of force is Newton (N).

One Newton is that force that when acting on a body of mass $1kg$.

It produces an acceleration of $1m{s}^{-2}$ in it.

C.G.S, unit of force is dyne.

One dyne is that force that when acting on a body of mass $1gram$.

and produces an acceleration of $1cm{s}^{-2}$ in it.

Therefore, $1Newton={10}^{5}dyne$
