FAQs on Physical World-- Class- 11-- Physics-- Chapter 1-- NCERT -- Fundamental Forces In Nature - CBSE Video Lecture - Class 11
| 1. What are the four fundamental forces in nature? |  |
Ans. The four fundamental forces in nature are gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force. Gravitational force is responsible for the attraction between two masses, electromagnetic force is responsible for the interaction between charged particles, strong nuclear force holds the nucleus of an atom together, and weak nuclear force is involved in radioactive decay.
| 2. How is the gravitational force different from the other fundamental forces? | |
Ans. The gravitational force is different from the other fundamental forces in several ways. Firstly, it is the weakest force among all the fundamental forces. Secondly, it acts on all objects with mass, regardless of their charge or composition. Thirdly, it has an infinite range, meaning it acts between any two objects in the universe, no matter how far apart they are.
| 3. What is the role of electromagnetic force in our daily lives? | |
Ans. The electromagnetic force plays a vital role in our daily lives. It is responsible for the interactions between charged particles, which allows for the existence of atoms, molecules, and chemical reactions. It is also the force behind electricity and magnetism, enabling the functioning of electronic devices, communication systems, and power generation. Our sense of vision is also possible due to the electromagnetic force, as it is responsible for the interaction of light with our eyes.
| 4. How does the strong nuclear force hold the nucleus of an atom together? | |
Ans. The strong nuclear force is responsible for holding the nucleus of an atom together. It is a short-range force that acts between the protons and neutrons in the nucleus. Despite the repulsive electromagnetic force between the positively charged protons, the strong nuclear force overcomes this repulsion and binds the protons and neutrons together. This force is stronger than the electromagnetic force at short distances, making it essential for the stability of atomic nuclei.
| 5. What is the significance of weak nuclear force in radioactive decay? | |
Ans. The weak nuclear force plays a significant role in radioactive decay. It is responsible for the transformation of one type of elementary particle into another, leading to the emission of radiation. During radioactive decay, the weak nuclear force causes certain particles in the nucleus to change their identity, resulting in the release of energy in the form of alpha particles, beta particles, or gamma rays. This process is essential for the stability and balance of atomic nuclei.
