NEET Physics Mechanical Properties of Fluids Questions Solved

A barometer kept in a stationary elevator reads 76 cm. If the elevator starts accelerating up the reading will be
(a) Zero                                       (b) Equal to 76 cm
(c) More than 76 cm                     (d) Less than 76 cm

(d) h=Pρg  h1g. If lift moves upward with some acceleration then effective g increases. So the value of h decreases i.e. reading will be less than 76 cm.
