The position vector of a particle `vec(R )` as a funtion of time is given by:
`vec(R )= 4sin(2pit)hat(i)+4cos(2pit)hat(j)`
Where `R` is in meters, `t` is in seconds and `hat(i)` and `hat(j)` denote until vectors along x-and y- directions, respectively Which one of the following statements is wrong for the motion of particle ?

Options

A. Magnitude of the velocity of particle is 8 metre/second.
B. Path of the particle is a circle of radius 4 metre.
C. Acceleration vector is along `-vecR`.
D. Magnitude of acceleration vector is , where v is the velocity of particle.
