Question

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

• A. $a_{r}=0,a_{t}=0$
• B. $a_{r}≠0, \, \, a_{t}≠0$
• C. $a_{r}\neq 0 \, , \, a_{t}=0$
• D. $a_{r}=0, \, \, a_{t}≠0$

Answer 1

Answer: (C)

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