For a particle in uniform circular motion the acceleration a at a point P(R,θ) on the circle of radius R is (here 'v' is the speed of the particle and θ is measured from the x-axis)

Options

A. `(v^(2))/(R)hati+(v^(2))/(R)hatj`
B. `-(v^(2))/(R)costhetahati+(v^(2))/(R)sinthetahatj`
C. `-(v^(2))/(R)sinthetahati+(v^(2))/(R)costhetahatj`
D. `-(v^(2))/(R)costhetahati-(v^(2))/(R)sinthetahatj`

Answer

D
