For a particle moving in a circle with constant angular velocity, which of the following statements is false?

 

Option: 1

Velocity vector is tangent to circle

 

 


Option: 2

Acceleration vector is tangent to circle
 


Option: 3

Acceleration vector points to centre of circle
 


Option: 4

Velocity and acceleration vectors are perpendicular to each other

Option(2) is correct because it is wrong to say that the acceleration vector is tangent to the circle, because the acceleration vector in uniform circular motion is cantered, i.e., the axis points to the radial direction.

Choice (4) is incorrect because the centripetal acceleration always points to the centre of the circle. This statement is therefore correct.

Choice (3) is incorrect because the velocity vector is tangent to the circle and the centripetal acceleration points to the centre of the circle, which are perpendicular to each other. This statement is true.
