Question

A particle of mass m moves in a circle of radius r with
uniform speed v. Its linear velocity vector is along

The axis of rotation
The radius
The tangent
Roth (1) and (2)​

Answer 1

Answer:

It will be along the axis of rotation

Answer 2

Concept introduction:

The force that is applied inward toward the center of rotation and is required to keep an item moving along a curved path A stone is subjected to centripetal force when it is spun around on a string.

Explanation:

Given that, a particle of mass m moves in a circle of radius r with uniform speed v.

We have to find, direction of its  linear velocity vector.

According to the question,

In centripetal force velocity vector is directed towards tangent of the circle.

Final Answer:

c) The tangent.
