Chapter 4: Problem 107

Which of the following forces have an unlimited range: strong force, contact force, electromagnetic force, gravitational force?

Short Answer

Expert verified
Answer: The electromagnetic force and gravitational force have an unlimited range.

Step by step solution

01

Strong Force

The strong force is one of the four fundamental forces in nature. It acts at the subatomic level, holding the protons and neutrons together in the nucleus. However, the range of the strong force is limited. It only acts at very short distances (around 1 femtometer, or 10^-15 meters) within the nucleus, and its strength decreases significantly at greater distances.
02

Contact Force

Contact forces are those forces that involve physical contact between two interacting objects, such as the force exerted by a person pushing a box. The range of a contact force is limited because it can only act when the two objects are in direct contact with each other.
03

Electromagnetic Force

The electromagnetic force is another fundamental force that is responsible for the interactions between charged particles (e.g., protons and electrons). The electromagnetic force has an infinite range, as it acts between charged particles regardless of the distance between them. However, its strength decreases with increasing distance, according to Coulomb's law, which states that the force between two particles is inversely proportional to the square of the distance between them.
04

Gravitational Force

The gravitational force is the force that attracts objects with mass towards each other, as described by Newton's law of universal gravitation. This force also has an unlimited range, acting between any two objects with mass regardless of the distance between them. However, like the electromagnetic force, the strength of the gravitational force also decreases with increasing distance, following an inverse square law. In conclusion, out of the given forces, the electromagnetic and gravitational forces have an unlimited range.

A roller coaster is towed up an incline at a steady speed of $0.50 \mathrm{m} / \mathrm{s}$ by a chain parallel to the surface of the incline. The slope is \(3.0 \%,\) which means that the elevation increases by \(3.0 \mathrm{m}\) for every \(100.0 \mathrm{m}\) of horizontal distance. The mass of the roller coaster is \(400.0 \mathrm{kg}\). Ignoring friction, what is the magnitude of the force exerted on the roller coaster by the chain?
