Question

A particle, moving along a circular path has magnitudes of linear and angular acceleration. The diameter of path is (in meters)-

• A. $2$
• B. $1$
• C. $\pi$
• D. $2\pi$

Answer 1

The correct option is A $2$

As we know

$a=\alpha r$

Where $r$ is radius

$a$ is linear acceleration

$\alpha$ is angular acceleration

$⟹r=1/m⟹d=2m$
