In Fig, what will be the sign of the velocity of the point P′ , which is the projection of the velocity of the reference particle P . P is moving in a circle of radius R in anticlockwise direction.
This is a multiple choice answer as classified in NCERT Exemplar
As the particle on reference circle moves in anticlockwise direction. The projection will move from P to O towards left.
Hence in the position shown the velocity is directed from P’ to P’’ i.e from right to left . hence sign is negative.
