Aeroplane flying at a constant velocity releases a bomb

 # An aeroplane flying at a constant velocity releases a bomb. As the bomb drops down from the aeroplane, 
A. it will always be vertically below the aeroplane
B. it will always be vertically below the aeroplane only if the aeroplane is flying horizontally
C. it will always be vertically below the aeroplane only if the aeroplane is flying at an angle of 45° to the horizontal
D. it will gradually fall behind the aeroplane if the aeroplane is flying horizontally



The correct answer is A. it will always be vertically below the aeroplane

The horizontal component of the velocity of the bomb is the same as the horizontal component of the velocity of the aeroplane in all cases. Hence, in all cases, the two have the same horizontal displacement in the same time.
