A man is standing on a weighing machine placed in a lift. When Stationary, his weight is recorded as 40 kg. If the lift is moved upwards with an acceleration of 2 ms –2 , then the weight recorded in the machine will be -(g = 10 ms –2 )
Text Solution
Verified by ExpertsThe correct answer is:
D
N = m (g + a) or N = 40 (10 + 2)
or N = 480 newton or N = 48 kg - wt.
