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

A

`45^(@)`

B

`60^(@)`

C

`0^(@)`

D

`30^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B

Let the particle moving in a straight line makes an angle `theta` with x-axis.
slope = `tan theta=(y)/(x)=(3)/(sqrt(3))`
Since, `tan theta=sqrt(3),theta=60^(@)`
