1.	In the figure, what will be the sign of the velocity of the point P_1, which is the projection of the velocity of the reference particle P. P is moving in a circle of radius R in anti-clockwise direction. .
Answer» Solution :As the particle on reference CIRCLE MOVES in anti-clockwise direction. The projection on x-axis will COME from `P_1` to O towards left. Means from right to left, hence sign is negative. .
