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

1.	The position vector of a particlevecR as a fuction of time is given by : vecR = 4sin(2 pi t)hat(i) + 4cos(2 pi i) hat(j). Where R is in meters,t is in seconds and hat(i) and hat(j) denote unit vectors along x- and y - directions, respectively. Which one of the following statements is wrong for the motion of particle?
Answer» 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. Answer :D
