Question

When a force is applied on 2 kg and 4 kg masses one after another, the acceleration produced on them are 2 m/s2 and 1 m/s2 respectively. What is the magnitude of that force?

Answer 1

Explanation:

We know that,

$\rm \vec{F}= m \vec{a}$

$\sf (a)$

$\rm \mid \vec{F} \mid = 2×2=4 \: N$

$\sf (b)$

$\rm \mid \vec{F} \mid = 4×1=4 \: N$
