Question

Ramu applied a force of 10 N on a body to move it from rest. He wants to express the applied force is in terms of various system of units. Expression of 10 N force in terms of dynes :

• A. ${10}^5$
• B. ${10}^6$
• C. ${10}^7$
• D. ${10}^8$

Answer 1

The correct option is B ${10}^6$

$1Newton=1kg\times 1m/s^2$

$=1000g\times 100cm/s^2$

$=100000gcm/s^2$

$={10}^{5}dyne$ (Since we know $1dyne=gcm/s^2$)

So,

$10Newton=10\times {10}^5={10}^{6}dynes$
