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 for 10 N force is :

• A. 98 kgf
• B. 1 kgf
• C. 100 kgf
• D. 9.8 kgf

Answer 1

Answer: (B)

1 kgf

From Newton's second law of motion,

$F=ma$

where,

$F$ is force

$m$ is mass

$a$ is accleration due to gravity

Taking the value of $m$ as $1kg$ and $a$ as $10m/s^2$

Then,

$F=1kg\times 10m/s^2$

Hence, $1kgf=10N$
