A man whose mass is 70kg stands on a weighing machine inside a lift moving upwards with uniform velocity.What is the reading on the machine (g = 10 ms-²
The normal force acting on the man when he is standing on the weighing machine inside the lift is equal to his weight.
Weight = mass x acceleration due to gravity
Weight = 70kg x 10 ms^-2
Weight = 700 N
Therefore, the reading on the weighing machine when the man is standing inside the lift moving upwards with uniform velocity would be 700 N.
