A body of mass $4 \,kg$ weighs $4.8\,kg$ when suspended in a moving lift. The acceleration of the lift is
$9.80\,m{s^{ - 2}}$ downwards
$9.80$$m{s^{ - 2}}$ upwards
$1.96$$m{s^{ - 2}}$ downwards
$1.96$$m{s^{ - 2}}$ upwards
A body of mass $4 \,kg$ weighs $4.8\,kg$ when suspended in a moving lift. The acceleration of the lift is
As the apparent weight increase therefore we can say that acceleration of the lift is in upward direction.
$R = m(g + a)$ $⇒$ $4.8\;g = 4(g + a)$
$⇒$ $a = 0.2\,g = 1.96\;m/{s^2}$
