Answer 2

Solution : 

Let P¯¯¯P¯ be as shown in the figure, then according to the given information.

Px=5,Py=6Px=5,Py=6

∣∣P¯¯¯∣∣=P2x+P2y−−−−−−−√|P¯|=Px2+Py2

25+36−−−−−−√25+36

∣∣P¯¯¯∣∣=61−−√|P¯|=61

And tanθ=PyPx=65tanθ=PyPx=65

⇒θ=tan−1(65)⇒θ=tan-1(65)

=50.19∘=50.19∘

Thus P¯¯¯P¯ having magnitude 61−−√61 lies in x -y plane at an angle 50.19∘50.19∘ to the x-axis.
