Question

A man is standing on a weighing machine placed in a lift. When lift is stationary his weight is recorded as
40 kg. If the lift is accelerated upwards with an acceleration of 2 m/s2, then the weight recorded in the
machine will be- (g = 10 m/s)
(1) 32 kg
(2) 40 kg
(3) 42 kg
(4) 48 kg
​

Answer 1

Answer:

Explanation:

The answer is 40 kg because mass does not depend upon acc.

If we have to calculate weight then resultant acc is 10+2=12 m/s²

And wt. Will be 12*40= 480 N

But mass is 40 kg

Ans is "c"
