Question

If x component of a vector is 3N and y component is -3N, then angle of the resultant vector with x-axis will be?? How to solve?

Answer 1

Explanation:

ANSWER

Component of vector r in x direction, ∣r

x

∣=rcosθ

where θ is the angle between

r

and x axis

As ∣r

x

∣ is maximum, thus rcosθ is maximum.

This is possible only when cosθ=1

⟹ θ=0

o

Hence,

r

is along +ve x-axis.
