The x- component of a certain vector in ...

The `x-` component of a certain vector in `x-y` plane is 2 units and `y-` component is `+2sqrt(3)` units. What is the magnitude of the vector.

Text Solution

Verified by Experts

The correct Answer is:
`4`
`A_(x) = 2`
`A_(y) = 2sqrt(3)`
`A = sqrt(Ax^(2) + Ay^(2)) = sqrt(4 +12) = 4`
