Q. In uniform circular motion of a particle
KEAM
KEAM 2008
Motion in a Plane
A
velocity is constant but acceleration is variable
32%
B
velocity is variable but acceleration is constant
24%
C
both speed and acceleration are constants
20%
D
speed is constant but acceleration is variable
19%
Solution:
In uniform circular, speed of particle is constant. Therefore, tangential acceleration is zero but radial acceleration remains which is constant in magnitude but its direction changes as particle moves in circular path.
