Which one is not correct for a cyclic process as shown in the figure ?

Options

A. Height of column of liquid `A` is greater than that of `C`.
B. Density of liquid `A` is less than that of liquid `C`.
C. Density of liquid `B` is maximum among these three liquids.
D. Pressure at `R` is greater than that at `S`.

Answer

B, C

Explanation

Since the liquids are instatic equilibrium, pressure at `R=` pressure at `S`. Since liquid `A` is above liquid `B`, density of liquid `A` is less than that of `B`. Similarly density of liquid `C` is less three liquids. Hence option `c` is correct. ltbr. Since `T` is at lower leve than `Q` the pressure exerted by `C` is greater than that exerted by A`. It is possible only when density of liquid `A` is less than that of `C`.Hence, option `b` is correct.
