When the angle of the ramp increases, the weight of the box acting perpendicular to the ramp decreases.

Normal reaction of the box

The normal reaction of the box is due to weight of the box acting perpendicular to the ramp.

Fn = Wcosθ

when the angle of the ramp = 30⁰

Fn = Wcos(30)

Fn = 0.866W

when the angle of the ramp = 45⁰

Fn = W x cos(45)

Fn = 0.7071W

Thus, when the angle of the ramp increases, the weight of the box acting perpendicular to the ramp decreases.
