Physics Laws of Motion MHT CET 2024

For a particle in uniform circular motion has

(1)linear velocity always radial to the circular path, without change in its magnitude
(2)linear velocity always tangential to the circular path, without change in its magnitudeCorrect
(3)linear acceleration always tangential to the circular path
(4)linear acceleration always along the axis of the circular path

Answer: (2)

Solution

In uniform circular motion the speed is constant, and at every instant the velocity vector is directed along the tangent to the circle, i.e. perpendicular to the radius. The direction of velocity changes continuously but its magnitude does not. The only acceleration is the centripetal acceleration $a =
