Apparent Weight & Lift

A man weight 80 kg. He stands on a weighting scale in a lift which is moving upwards with a uniform acceleration of 5 m/s2. What would be the reading on the scale? (g = 10 m/s2)

Show answer and solution

Answer: (d)

Lift accelerating up: $N = m(g + a)$ .
$N = 80 \times (10 + 5) = 1200$ N
So the answer is (d) 1200 N.
