Question

A particle is having uniform circular motion of radius r and angular velocity $\omega$. The magnitude of the change in acceleration while the particle completes half a revolution is

• A. Zero
• B. $r{\omega }^2$
• C. $2r{\omega }^2$
• D. $\sqrt{(}2)r{\omega }^2$

Answer 1

The correct option is A Zero

The acceleration of a particle in a uniform circular motion is given by $r{\omega }^2$ and its direction is towards the circle.
If magnitude is only considered, then their difference is zero
