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 the `X`-axis

D

`vecr` is along negitive `Y`-axis

Text Solution

Verified by Experts

The correct Answer is:
B
Let `r` makes an angle `theta` with positive `x`-axis component of `r` along `x`-axis
`{:(r_(x),=|r|,costheta),(r_("maximum"),=|r|,(costheta)),(theta,=|r|,cos0^(@)=|r|):}`
( `:' cos theta` is maximum of `theta=0^(@)`)
`r` is along positive x-axis.
