The component of a vector `vec(r)` along x- axis will have a maximum value if

A

`vecr` is along `+ve` x - axis

B

`vecr` is along `+ve` y - axis

C

`vecr` is along `-ve` y - axis

D

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

Text Solution

Verified by Experts

The correct Answer is:
A
`r_(x)=rcostheta`
`r_(x)` is maximum if `theta=0^(@)`
