If the resultant of the following forces is zero, find the value of `F_(0)`.

Explanation

If a vector is zero , its components are zero.
If `vec(A) = 0 , i.e. A_(x) = 0 , A_(y) = 0 , A_(z) = 0`
In this problem , the `x`-component of the resultant force
`F_(x) = F_(0) cos 30^(@) - 2 sqrt(3) = 0`
`F_(0) (sqrt(3))/(2) - 2 sqrt(3) = 0 rArr F_(0) = 4 N`
