MCQ

During the motion of a lift, apparent weight of a body becomes twice its actual weight when,

A
Lift is moving down with acc. $= g.$
✓
Lift is moving up with acc. $= g.$
C
Lift is moving down with uniform velocity $= 9.8\ ms^{-1}$.
D
Lift is moving up with uniform velocity $= ms^{-1}$.

✓

Answer

Correct option: B.

Lift is moving up with acc. $= g.$

Apparent weight $=\text{m}(\text{g}\pm\text{a})$
Apparent weight $= m(g + g) = 2mg$

The ratio of surface tensions of mercury and water is given to be $7.5$ while the ratio of their densities is $13.6$. Their contact angles, with glass, are close to $135^o$ and $0^o$, respectively. It is observed that mercury gets depressed by an amount $h$ in a capillary tube of radius $r_1$, while water rises by the same amount $h$ in a capillary tube of radius $r_2$. The ratio, $(r_1/r_2)$, is then close to
