Awoman falls to the ground while wearing a parachute. the air resistance on the parachute is 500n. if the woman falls at a constant rate of 5 m/s, then the gravitational force on her is

Then the gravitational force on her should be equal to the air resistance, i.e. 500 N.
In fact, the woman is falling at constant velocity, 5 m/s. This means there is no acceleration on her. But Netwon's second law states that the resultant of the forces acting on the body is equal to the product between the mass and the accleration:

But the acceleration is zero, so the resultant of the forces acting on the woman must be zero. Since only two forces are acting (the air resistance, upward, and the gravity, downward) and they are in opposite direction, they must have equal intensity in order to produce a net acceleration of zero, so they both have intensity of 500 N.

Answer

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

explanation

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
