Question

The force acting on a mass of 1 g due to the gravitational pull on the earth is called 1 g-wt. One g-wt equals :

• A. 1N
• B. 9.8N
• C. 980 dyne
• D. None of these

Answer 1

Answer: (C)

980 dyne

$1gwt=0.001kg\times 9.8m/s^2=0.0098N$

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

$\Rightarrow 1gwt=980dyne$

Hence correct answer is option $C$
