NEET circular motion questions

A particle shows uniform circular motion. Its motion is .

(A) : Force is required to move a body uniformly along a circle. (R) : When the body is in uniform circular motion, acceleration is zero.

A body executing uniform circular motion has its position vector and acceleration vector

Assertion: Electron moving perpendicular to vecB will perform circular motion. Reason: Force by magnetic field is perpendicular to velocity.

Assertion uniform circular motion is uniformly accelerated motion. Reason acceleration in uniform circular motion is always towards centre.

In the following questions a statement of assertion (A) is followed by a statement of reason ( R). A : A uniform circular motion have non uniform acceleration . R: The direction of acceleration of a particle in uniform circular motion changes continuously .

Is a body in uniform circular motion in equilibrium ?

Assertion : We can call circular motion also as simple harmonic motion. Reason : Angular velocity in uniform circular motion and angular frequency in simple harmonic motion have the same meanings.

Is the acceleration of particle in uniform circular motion constant or vartiable?

What is meant by circular motion? Give one example.
