The velocity and acceleration vectors of a particle undergoing circular motion are v =2 i m / s and a =2 i +4 j m / s ² respectively at an instant of time. The radius of the circle is -

Options

  1. A1 ~m
  2. B2 ~m
  3. C3 ~m
  4. D4 ~m

Correct answer

A. 1 ~m

Step-by-step solution

It can be observed that component of acceleration perpendicular to velocity is a =4 ~m / s ² radius = v ² a _ c = (2)² 4 =1 metre
