Circular MotionHard
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
= 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 =
= = 1m.Create a free account to view solution
