FAQs on NCERT Solutions for Class 11 Physics Chapter 9

Q.1: What is a Deforming Force?

Ans: A deforming force is a force that produces a change in the configuration of the object on which it is applied.

Q.2: What is Poisson’s Ratio?

Ans: The ratio of the lateral strain to the longitudinal strain in a stretched wire is referred to as Poisson’s Ratio. The equation is given as (Δd/d)/(ΔL/L).

Q.3: What are the 2 types of stress?

Ans: The two types of stress are Normal Stress and Tangential Stress. When the stress is applied to an area it is referred to as normal stress. when the deforming stress is applied tangentially it is called Tangential stress.

Q.4: What is Hooke’s Law?

Ans: Within the limits of elasticity, the stress produced in a solid is directly proportional to the strain.

Q.5: What are the benefits of solving NCERT Class 11 Physics solutions?

Ans: By solving the NCERT solutions for Class 11 Physics, students can enhance their confidence levels, perform well in the exams, attain proficiency in the important topics of the subject and build the required fundamentals for competitive exams.
