# HC Verma The Forces Solutions (Chapter 4)

HC Verma Chapter 4 Solutions explains the topics about the various forces that are taking place in our world around us. The force of gravitation and the force of attraction are some of the significant forces that manage the laws of physics here on planet Earth. With the help of these HC Verma Solutions for Class 11 Physics Part – 1 Solutions, you can learn about the various forces that control our universe.

The main topics of the HC Verma The Forces Solutions include gravitational force, electromagnetic force, nuclear forces, weak forces, and scope of classical physics. This chapter also illustrates some interesting concepts which are developed in the numerical problems including the weight of the earth, the mass of earth, the radius of the earth, the mass of the satellite, Coulomb’s Force, etc. There are a total of 12 problems available based on these important topics of the chapter. You can also increase your problem-solving efficiency by referring to the solved examples given in the chapter and practising them.

All these solutions are developed by expert Physics teachers who have broadened and simplified the concepts of HC Verma The Forces Solutions for better understanding. Also, in these solutions, even the most difficult problem has been broken down to make your learning easier. So, you can follow these solutions provided by Instasolv for free.

## Important Topics for HC Verma Solutions for Class 11 Physics Chapter 4 – The Forces

Gravitational Force

The gravitational force is a force that appeals to any two substances with mass. In fact, every item, counting you, is pulling on every other entity in the complete universe! This is also considered as Newton’s Universal Law of Gravitation.

Electromagnetic Force

The electromagnetic force is a force that happens between electrically charged elements, such as electrons, and is referred to electrostatics as being either positive or negative. Substances with opposite charges generate an attractive force between them, while substances with the same charge generate a repulsive force.

Nuclear Forces

Nuclear forces are also called nuclear interactions or strong forces. These are HC Verma The Forces Solutions that act between two or more neutrons. They bind protons and neutrons into atomic nuclei. The nuclear force is around 10 million times stronger than the chemical binding that grips atoms together in molecules.

Weak Forces

The weak interaction is also known as a weak force or weak nuclear force. These are the fundamental forces of nature that bring about some forms of radioactivity, rule the falling-off unbalanced subatomic elements such as mesons, and recruit the nuclear fusion reaction that fuels the Sun.

Mass of Satellite

The term “small satellite”, or “minisatellite”, often mentions an artificial satellite with a wet mass between 100 and 500 kg, but in other practice has come to mean any satellite under 500 kg.

Coulomb’s Force

The Coulomb force between two or more charged entities is the force between them due to Coulomb’s law. If the elements are both positively and negatively charged, then the force is considered as repulsive but if the elements are of opposite charge then they are attractive.

Earth radius is the distance between the centre of Earth to a point on its surface. Its significance ranges from 6,378 km at the equator to 6,357 km at a pole. A nominal Earth radius is at times used as a unit of measurement in astronomy.
