A man of weight 75 kg is standing in an elevator which is moving with an acceleration of 5 m/s2 in upward direction the apparent weight of the man will be: (g=10 m/s2)

Question

A man of weight 75 kg is standing in an elevator which is moving with an acceleration of 5 m/s2 in upward direction the apparent weight of the man will be: (g=10 m/s2) (A) 1425 N (B) 1375 N (C) 1250 N (D) 1125 N

Tardigrade Admin · Accepted Answer

Here: Mass of the man m=75 kg Acceleration of elevator a=5 m / s The apparent weight of the man is W =m(g +a)=75 ×(10+5) =1125 N

Q. A man of weight $75 k g$ is standing in an elevator which is moving with an acceleration of $5 m / s^{2}$ in upward direction the apparent weight of the man will be: $(g = 10 m / s^{2})$

1425 N

1375 N

1250 N

1125 N

Here : Mass of the man $m = 75 k g$
Acceleration of elevator $a = 5 m / s$
The apparent weight of the man is
$W = m (g + a) = 75 \times (10 + 5)$
$= 1125 N$
