2. Assertion (A): Any ray of light suffers a deviation of \(180° - 2i\) after one reflection from plane mirror. Reason (R): For normal incidence of light on the plane mirror deviation is zero.  
3. A plane mirror is placed along the x-axis facing negative y-axis. The mirror is fixed. A point object is moving with \[3\hat{i}+4\hat{j}\] in front of the plane mirror. The relative velocity of image with respect to its object is :
