Question

Find the value of `x` and `y`. so that the vectors `2hatj + 3hatj` and `xhati + yhati` are equal

पर्याय

• `x` = 2, `y` = 4

• `x` = 3, `y` = 9

• `x` = 2, `y` = 3

• `x` = 1, `y` = 1

Answer 1

`x` = 2, `y` = 3

Explanation:

`2hati + 3hatj = xhati + yhatj`

Equating the coefficient of `hati` and `hatj`

`x` = 2, `y` = 3.
