Question

1 Newton $=$

• A. ${10}^{4}dyne$
• B. ${10}^{5}dyne$
• C. ${10}^{6}dyne$
• D. ${10}^{7}dyne$

Answer 1

The correct option is B ${10}^{5}dyne$

S.I. unit of force is Newton and CGS unit of force is done.

We know $F=ma$

so, force can be expresses in S.I. Units as $Kgm{s}^{-2}$

and dyne can be expressed as $gcm{s}^{-2}$

1 Newton= $kgm{s}^{-2}$

=${10}^{3}g\ast {10}^{2}cms{s}^{-2}$

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

=${10}^{5}dyne$
