For a particle in uniform circular motion , the acceleration ` vec(a)` at a point ` p ( R, theta )` on the circle of radiu ` R` is ( Here ` theta` is measured from the ` x- axis` )

Options

A. `- (v^(2))/(R ) cos theta hat(i) + (v^(2))/(R ) sin theta hat(j)`
B. `- (v^(2))/(R ) sin theta hat(i) + (v^(2))/(R ) cos theta hat(j)`
C. `- (v^(2))/(R ) cos theta hat(i) - (v^(2))/(R ) sin theta hat(j)`
D. `(v^(2))/(R ) hat(i) + (v^(2))/(R ) hat(j)`

Answer

C
