MCQ
A bomb is dropped from an aeroplane moving horizontally at constant speed. When air resistance is taken into consideration, the bomb
  • A
    Falls to earth exactly below the aeroplane
  • Fall to earth behind the aeroplane
  • C
    Falls to earth ahead of the aeroplane
  • D
    Flies with the aeroplane

Answer

Correct option: B.
Fall to earth behind the aeroplane
b
(b)Due to air resistance, it’s horizontal velocity will decrease so it will fall behind the aeroplane.
