The velocity and acceleration vectors of a particle undergoing circular motion are v → = 2 i ^ m s - 1 and a → = 2 i ^ + 4 j ^ m s - 2 respectively at an instant of time. What is the radius (in m ) of the circle?
Correct answer
1
Step-by-step solution
It can be observed that the component of acceleration perpendicular to velocity is a = 4   m   s - 2 ∴    Radius = v 2 a c = 2 2 4 = 1   m
