Question

A body of mass 1.0 kg is falling with an acceleration of $10m/s^2$. Its apparent weight will be $(g=10m/s^2)$

• A. $2.0kg-wt$
• B. $1.0kg-wt$
• C. $0.5kg-wt$
• D. zero

Answer 1

The correct option is D zero

Given,

$m=1.0kg$

$a=10m/s^2$

$g=10m/s^2$

The pseudo force acting on the body is acting in an upward direction.

So, the apparent weight will be

$W^{\prime }=m(g-a)$

$W^{\prime }=1(10-10)=1\times 0$

$W^{\prime }=0kg-wt$

The correct option is D.
