MCQ
A closed compartment containing gas is moving with some acceleration in horizontal direction. Neglect effect of gravity. Then the pressure in the compartment is
  • A
    Same everywhere
  • Lower in the front side
  • C
    Lower in the rear side
  • D
    Lower in the upper side

Answer

Correct option: B.
Lower in the front side
b
The pressure in the front part of the closed compartment will be less because in the accelerated frame the pseudo force will act on the molecules backwards and the density of the gas will be more backwards
