The position vector of a particle $\overrightarrow{R}$ as a function of time is given by: $\bar{R}$ = 4 sin(2$\pi$t) $\hat{l}$ + 4cos (2$\pi$t)$\hat{j}$ Where R is in meters, t is in seconds and $\hat{l}$ 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?
