If \(\vec{r}\) is the position vector of a particle at time t, \(\vec{r'}\) is the position vector of the particle at time \(t'\), and \(\Delta \vec{r}\) is the displacement vector, then instantaneous velocity is given by
Choose Your Option
A. \(V = \lim_{\Delta t\to 0}\frac{\Delta \vec{r'}}{\Delta t}\)
B. \(V = \lim_{\Delta t\to 0}\frac{\Delta \vec{r}}{\Delta t}\)
