Question

At the top of the trajectory of a projectile, the direction of its velocity and acceleration are

  1. perpendicular to each other  
  2. parallel to each other  
  3. inclined to each other at angle of 45 degree  
  4. antiparallel to each other  

The correct answer is: perpendicular to each other


    Direction of velocity is always tangent to path, so at the top of trajectory it is in horizontal direction and acceleration due to gravity is always in vertically downward direction. Hence, v and g are perpendicular to each other.
