The unit vector bisecting vec(OY) and ve...

The unit vector bisecting `vec(OY)` and `vec(OZ)` is

A

`(veci+vecj+veck)/sqrt(3)`

B

`(veci-veck)/sqrt(2)`

C

`(vecj+veck)/sqrt(2)`

D

`(-vecj+veck)/sqrt(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`hatj` and `hatk` are unit vectors along `Y-` and `Z-` axes, then unit vector bisecting `vec(OY)` and `vec(OZ)` is `(hati+hatk)/sqrt(2)`
