MCQ
A flag is mounted on a car moving due North with velocity of $20 \,\,km/hr$ Strong winds are blowing due East with velocity of $20\,\,km/hr$. The flag will point in direction
  • A
    East
  • B
    North - East
  • ✓
    South - East
  • D
    South - West
✓

Answer

Correct option: C.
South - East
c
since the car is moving in North, Thus, the flag will move in South direction because$=$ of the car. Now because of the wind the flag will change its direction towards east. Thus, its direction will be South$-$East.
