Question

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

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

Answer 1

Answer: (C)

$980dyne$

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

But we know that $1N={10}^{5}dyne$

$\Rightarrow 1gwt=980dyne$

Hence correct answer is option $C$
