A paricle starting from the origin (0,0)...

A paricle starting from the origin (0,0) moves in a straight line in `(x,y)` plane. Its coordinates at a later time are `(sqrt(3),3)`. The path of the particle makes with the x-axis an angle of

Text Solution

Verified by Experts

The correct Answer is:
C
`tan theta= (PQ)/(OQ)`
`rArr theta= tan^(-1) ((3)/(sqrt3))`
