Circular MotionMedium
Question
The velocity and acceleration vectors of a particle undergoing circular motion are
= 2î m/s and
= 2î + 4ĵ m/s2 respectively at an instant of time. The radius of the circle is
Options
A.1m
B.2m
C.3m
D.4m
Solution
It can be observed that component of acceleration perpendicular to velocity is
ac = 4 m/s2
∴ radius =
=
= 1m.
ac = 4 m/s2
∴ radius =
