In Figure What Will Be The Sign Of The Velocity Of The Point P’ Which Is The Projection Of The Velocity Of The Reference Particle P

In figure, what will be the sign of the velocity of the point P’, which is the projection of … in a circle of radius R in…


As the particle on reference circle moves in anti-clockwise direction. The projection will move from P’ to O towards left, i.e. from right to left, hence sign is negative.
