Assuming you're working in a 3D cartesian coordinate system, i.e. each point in space has an x, y, and z coordinate, you add up the forces' x/y/z components to find the resultant force.
Answer:

Explanation:
given
wavelength of light λ = 479 nm
= 479 x 10⁻⁹ m
the angle
θ = 1.15 / 2 = 0.575°
using
condition for diffraction minimum ,
d sinθ = m λ
for first minimum m = 1
d sinθ = λ
therefore ,
slit width

hence, the width of the slit is equal to
