# NEET Physics Mechanical Properties of Fluids Questions Solved

Three liquids of densities  (with ${p}_{1}>{p}_{2}>{p}_{3}$), having the same value of surface tension T, rise to the same height in three identical capillaries. The angles of contact  obey

(a) $\frac{\pi }{2}>{\theta }_{1}>{\theta }_{2}>{\theta }_{3}\ge 0$

(b) $0\le {\theta }_{1}<{\theta }_{2}<{\theta }_{3}<\frac{\pi }{2}$

(c) $\frac{\pi }{2}<{\theta }_{1}<{\theta }_{2}<{\theta }_{3}<\pi$

(d) $\pi >{\theta }_{1}>{\theta }_{2}>{\theta }_{3}>\frac{\pi }{2}$
