The weight of a man in a lift moving upwards with an acceleration ' $a$ ' is $620 N$ . When the lift moves downwards with the same acceleration, his weight is found to be $340 N$ . The real weight of the man is

Options:

Answer:

Solution:

$m (g + a) = 620 N m (g - a) = 340 n \Rightarrow \frac{g + a}{g - a} = \frac{620}{340} a = \frac{7}{24} g$ Hence, from eq.(i) actual weight $mg = 480 N$
