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

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

A

`vecr` is along positive Y-axis

B

`vecr` is along positive X-axis

C

`vecr` makes an angle of `45^(@)` with X-axis

D

`vec r` is along negative Y-axis

Text Solution

Verified by Experts

The correct Answer is:
B
(b): The components of `vecr` along X-axis is given by
`r_(x)=r cos theta`
`(r_(x))_("max")=r(cos theta)_("max")`
`=|vecr|`
As `theta=0`, so `vec r` is along X-axis .
The correct option is (b).
