AIPMT Prelims 2009 Physics Second Law of Motion MCQ Question with Solution

A body, under the action of a force $\vec{F} = 6 \hat{i} - 8 \hat{j} + 10 \hat{k}$ , acquires an acceleration of 1 m/s². The mass of this body must be:

A

10 kg

B

20 kg

C

10 $\sqrt{2}$ kg

D

2 $\sqrt{10}$ kg

Correct Answer

Option C

Detailed Explanation

The magnitude of the force is calculated as $|\vec{F}| = \sqrt{6^2 + (-8)^2 + 10^2} = 10\sqrt{2} \, \text{N}$ . With acceleration $a = 1 \, \text{m/s}^2$ , the mass $m = \frac{|\vec{F}|}{a} = 10\sqrt{2} \, \text{kg}$ .
