Question

State whether true or False
10 mN is equal to ${10}^{-3}$ dynes.

• A. True
• B. False

Answer 1

The correct option is B False

Newton (N) is a SI unit of Force while dyne is a CGS unit of force.

Relation between them is given as

$1dyne=1\ast {10}^{-3}\ast 1\ast {10}^{-2}N$

$1dyne={10}^{-5}N$

$1N={10}^{5}dyne$

$10mN=10\times {10}^{-3}N={10}^{-2}N={10}^{-2}\times {10}^{5}dyne$

$10mN={10}^{3}dyne$
