A closed compartment containing gas is moving with some acceleration in horziontal direction. Neglect effect of gravity. Then the pressure in the compartment is

same everywhere

lower in the front side

lower in the rear side

lower in the upper side

Text Solution

Verified by Experts

The correct Answer is:

If a fluid is accelerated in +x direction, then pressure decreases in that direction. The change of pressure is described by the following differential equation ,
`(dP)/(dx)=-rhoa` where `rho` is density of gas
Hence the pressure is lower in front side.

A closed rectangular tank 10 m long, 5 m wide and 3 m deep is completely filled with an oil of specific gravity 0.92 . Find the pressure difference between the rear and front corners of the tank, if it is moving with an acceleration of 3m//s^(2) in the horizontal direction.

A plumb bob is hung from the ceiling of a train compartment. If the train moves with an acceleration a along a straight horizontal track, the string supporting the bob makes an angle tan^1 (a/g) with the normal to the ceiling. Suppose the train moves on an inclined straight track with uniform velocity, if the angle of incline is tan^-1(a/g) , the string again makes the same angle with the normal to the ceiling. Can a person sitting inside the compartment tell by looking at the plumb line whether the train is accelerated on a horizontal straight track or it is going on an incline? If yes, how? If no, suggest a method to do so.

In the figure the top view of a compartment of a train is shown. A man is sitting at a corner 'B' of the compartment . The man throws a ball ( with respect to himself ) along the surface of the floor towards the corner 'D' of the compartment of the train.
