Q. If $a_{r}$ and $a_{t}$ represent radial and tangential accelerations, the motion of a particle will be uniformly circular if

NTA AbhyasNTA Abhyas 2022 Report Error

A

$a_{r}=0,a_{t}=0$

B

$a_{r}≠0, \, \, a_{t}≠0$

C

$a_{r}\neq 0 \, , \, a_{t}=0$

D

$a_{r}=0, \, \, a_{t}≠0$

Solution:

For uniform circular motion, tangential acceleration is zero while the radial acceleration is non zero.
$a_{t}=0,a_{r}\neq 0$
