The angle that the vector `vecA=2hati+3hatj` makes with y-axis is :

A

`tan^(-1)(3//2)`

B

`tan^(-1)(2//3)`

C

`sin^(-1) (2//3)`

D

`cos^(-1)(3//2)`

Text Solution

Verified by Experts

The correct Answer is:
2
Angle with y-axis `rArr tan theta = (x-"comp")/(y-"comp")= (2)/(3)`
`" "rArr theta = tan^(-1) ((2)/(3))`
