Question

A man of mass $60 \mathrm{~kg}$ records his wt. on a weighing machine placed inside a lift. The ratio of wts. of man recorded when lift is ascending up with a uniform speed of $2 \mathrm{~m} / \mathrm{s}$ to when it is descending down with a uniform speed of $4 \mathrm{~m} / \mathrm{s}$ will be, 0.5, 1, 2, none of these

Uniform speed will not affect his weight. The ratio is $\frac{60 \times g}{60 \times g}=1$
