Which of the following statements is FALSE for a paricle moving in a circle with a constant angular sppeed?A. The velcoity vector is tangent to the circleB. The acceleration vector is tangent to the circleC. The acceleration vector point to the cnetre of the circleD. The velocity and acceleration vectors are perpendicular to each other |
Answer» Correct Answer - B For a particle moving in a circle with constant angular speed, velocity vector is always tangent to the circle and the acceleration vector always points towards the centre of circle or is always point towards the centre of circle or is always along radius of he circle. since, tangential vector is prependicular to raidal vector, therefore, velocity vector will be perpendicular to the acceleration vector. But is no case acceleration vector is tangent to the circle |
