The component of a vector r along X-axis...

The component of a vector `r` along X-axis will have maximum value if

A

(a) ` vec r` is along positve Y-axis

B

(b) ` vec r` is along positve X-axis

C

(c ) `vec r` makes an angle of ` 45^@` with the X-axis

D

(d) ` vec r` is along negative Y-axis

Text Solution

Verified by Experts

The correct Answer is:
B
If ` vec r` makes an angle ` theta` with x-axis, theta component of ` vec r` is along x-axis = ` r cos theta`.
It will be maximum if ` cos = max =m 1` or ` theta0^2` i.e. vec r` along positve x-axis.
