Question

The mass of man when standing on the lift is 60 kg . The weight when the lift is moving upwards with acceleration 4.9 m s- 2 is (A) 882N (B) 600N (C) 306N (D) Zero

In case of upward motion F=m(g + a) =60(9.8 + 4.9) =60(14.7) =882 N

Q. The mass of man when standing on the lift is $60 k g$ . The weight when the lift is moving upwards with acceleration $4.9 m s^{- 2}$ is

$882 N$

$600 N$

$306 N$

Zero

In case of upward motion
$F = m (g + a)$
$= 60 (9.8 + 4.9)$
$= 60 (14.7)$
$= 882$ N
