(b) Forward direction

(c) Perpendicular direction

(d) Parallel movement

I have been asked this question by my college director while I was bunking the class.

I'm obligated to ask this question of Force Exerted by a Jet on a Stationary Curved Plate in portion Impact of Jets and Jet Propulsion of Fluid Mechanics

Answer 1

The correct answer is (b) Forward direction

To explain I would say: Force exerted by a jet on a moving plate happens in three cases. The three cases are classified depending on their position. The propulsive force drives the jet in the forward direction. A good example is the aircraft or a boat.
