The position vector of a particle `vecR` as a function of time is given by: `vecR=4sin(2pit)hati+4cos (2pit)hatj`where R is in meters,t is in second `hati`and`hatj`and denote unit vectors along x and y directions respectively Which one of the following statements is wrong for the motion for the motion of particle?

Path of the particle is a circle of radius 4 meter

Acceleration vectors is along - `vecR`

Magnitude of acceleration vector is `v^2/R` where v is the velocity of particle.

Magnitude of the velocity of particle is 8 `meter//second`
