A man of weight $75\,kg$ 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: $(g=10\,m/s^{2})$

• A. 1425 N
• B. 1375 N
• C. 1250 N
• D. 1125 N

Answer 1

Answer: (D)

1125 N

Answer 2

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