For a particle in uniform circular motion the acceleration ` vec a ` at a point ` P ( R, theta )` on the circle of radius R is : ( here ` theta ` is measured from the x- axis )

Options

A. `(v^(2))/(R) hati +(v^(2))/(R) hatj`
B. `-(v^(2))/(R) cos theta hati+(v^(2))/(R) sin theta hatj`
C. `-(v^(2))/(R)sin theta hati-(v^(2))/(R) cos theta hati`
D. `-(v^(2))/(R) cos thetahati-(v^(2))/(R) sin thetahatj`

Answer

C
