Mass of body, M=1 kg Falling acceleration of body, a=10 ms -2 g=10 ms -2 [∵ Here, a=g] ∴ Apparent weight =m(g-a)=m × 0=0 ∴ When body is falling with gravitational acceleration, then its apparent weight will be zero.

Q. Find the apparent weight of a body of mass $1.0 k g$ falling with an acceleration of $10 m \cdot s^{- 2}$ . $(g \approx 10 m \cdot s^{- 2})$

$1 k g wt$

$2 k g wt$

$0$

$0.5 k g wt$

Mass of body, $M = 1 k g$
Falling acceleration of body, $a = 10 m s^{- 2}$
$g = 10 m s^{- 2}$
$[∵$ Here, $a = g]$
$∴$ Apparent weight $= m (g - a) = m \times 0 = 0$
$∴$ When body is falling with gravitational acceleration, then its apparent weight will be zero.
