In the figure, link $$2$$ rotates with constant angular velocity $${{\omega _2}}$$. A slider link $$3$$ moves outwards with a constant relative velocity $${V_{Q/P,}}$$ where $$Q$$ is a point on slider $$3$$ and $$p$$ is a point on link $$2.$$ The magnitude and direction of Coriolis component of acceleration is given by A
$${2{\omega _2}}$$ $${V_{Q/P;}}$$ direction of $${V_{Q/P}}$$ rotated by $${90^ \circ }$$ in the direction of $${{\omega _2}}.$$
B
$${{\omega _2}}$$ $${V_{Q/P}};$$ direction of $${V_{Q/P}}$$ rotated by $${90^ \circ }$$ in the direction of $${{\omega _2}}.$$
C
$${2{\omega _2}}$$ $${V_{Q/P}};$$ direction of $${V_{Q/P}}$$ rotated by $${90^ \circ }$$ Opposite to the direction of $${{\omega _2}}.$$
