If a particle executes uniform circular motion in the xy plane in clock wise direction, then the angular velocity is in :

Answer»

`+`y DIRECTION
`+`z direction
`-`z direction
`-` x direction

Solution :`vec(v) = vec(r) XX vec(omega)`
` sin THETA = (vec(r) xx vec(omega))/(|vec(r) xx vec (omega)|)`
Here` theta = 90^(@) and hat(n)`acts along - z direction.
`:. - ` z AXIS
