Question

$1$ Newton$=$ $K$ dyne, then what is the value of $K$?

• A. $1$
• B. ${10}^2$
• C. ${10}^5$
• D. $10$

Answer 1

The correct option is C ${10}^5$

Newton is in SI units that is Kg metre per second whereas Dyne is in Gram centimetre per second.

We know that $1Kg=1000gm$ where as $1metre=100cm$.

Hence to convert from SI units to CGS unit, we will have to multiply by a factor that is $1000\times 100$.

$K={10}^5$
