Question

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` )
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 hatj`
D. `-(v^(2))/(R ) cos theta hati - (v^(2))/(R ) sin theta hatj`

Answer 1

Correct Answer - D

`a_(C) =- (V^(2))/(R ) cos theta hati - (V^(2))/(R ) sin theta hatj`
