easy

The average acceleration vector for a particle having a uniform circular motion is

AA constant vector of magnitude $\frac{{{v^2}}}{r}$

BA vector of magnitude $\frac{{{v^2}}}{r}$ directed normal to the plane of the given uniform circular motion

CEqual to the instantaneous acceleration vector at the start of the motion

DA null vector

Solution

(d)In complete revolution change in velocity becomes zero so average acceleration will be zero.

Motion in two dimensions, in a plane can be studied by expressing position, velocity and acceleration as vectors in cartesian co-ordinates $A=A_{x} \hat{i}+A_{y} \hat{j},$ where $\hat{i}$ and $\hat{\jmath}$ are unit vector along $x$ and $y$ – directions, respectively and $A_{x}$ and $A_{y}$ are corresponding components of $A$. Motion can also be studied by expressing vectors in circular polar co-ordinates as $\overrightarrow A \, = \,{A_r}\widehat r\,\, + \,{A_\theta }\hat \theta $ where $\hat{r}=\frac{r}{r}=\cos \theta \hat{i}+\sin \theta \hat{\jmath}$ and $\hat{\theta}=-\sin \theta \hat{i}+\cos \theta \hat{j}$ are unit vectors along direction in which $\hat{r}$ and $\hat{\theta}$ are increasing.
