Final answer:
The pressure required to rupture a human eyeball is approximately 6.8 Newtons (N).
Step-by-step explanation:
The eye is maintained by intraocular pressure, which is normally in the range of 12.0 to 24.0 mm Hg. However, in cases of glaucoma, the net pressure can be as high as 85.0 mm Hg, leading to permanent damage to the optic nerve. By calculating the force using the formula F = PA, where P is the pressure and A is the area of the eye, the approximate force needed to rupture the eye can be determined as 6.8 N.
