In cricket when a bowler produce reverse swing the ball will move towards______________?
Correct answer: A. The shinning side of the ball
- A. The shinning side of the ball
- B. Rough side
- C. The seam of the ball
- D. Goes straight
Explanation
In reverse swing, the ball moves towards its shiny side because the airflow and boundary-layer separation around an old, fast-moving ball produce greater pressure on the rough side. Students often choose the rough side by confusing reverse swing with the usual description of conventional swing.

About Fluid Drag
Fluid drag is the resistive force exerted by a liquid or gas on an object moving through it, and its value depends on speed, fluid density, shape and exposed area. Questions examine drag at low and high speeds, terminal velocity when drag balances weight, and the difference between drag and ordinary solid friction.
