 # HC Verma Solutions Vol 1 Chapter 2 Physics and Mathematics

HC Verma Solutions Vol 1 Chapter 2 – Physics and Mathematics are available for students who are looking to solve questions from the second chapter of HC Verma book. The solutions provided here are aimed at providing the best answers for class 11 physics students. The chapter mainly deals with mathematical formulas that are integrated with solving for different concepts in Physics. In this chapter, students further learn more in detail about different mathematical topics such as vectors, displacement vectors, resultant vectors, components and addition of vectors.

One of the more interesting concepts that this chapter teaches us, is using vectors for solving different problems related to certain shapes such as polygons and hexagons. Thus, this chapter is useful in teaching students about the different concepts of Physics and how we can use mathematical formulas to solve the different problems. Thus, a student needs to be prepared to solve different problems in the subject of Physics with the help of mathematics.

In chapter 2 students will learn about topics like;

1. Vectors and Scalars
2. Equality of Vectors
4. Multiplication of a Vector by a Number
5. Subtraction of Vectors
6. Resolution of Vectors
7. Dot Product or Scalar Product of Two Vectors
8. Cross Product or Vector Product of Two Vectors
9. Differential Calculus as Rate Measurer
10. Maxima and Minima
11. Integral Calculus
12. Significant Digits
13. Significant Digits in Calculations
14. Errors in Measurement

## Important Questions In Chapter 2

• When we say “direction of zero vector” does it have any physical
significance? Give your reasons in terms of velocity, force etc.
• Can a unit vector be formed by using or adding three unit vectors?
What will be your answer if two unit vectors are along the coordinate axes?
• A vector has which main component:
(a) always greater than its magnitude
(b) always less than its magnitude
(c) always equal to its magnitude
(d) none of these.
• Is it possible to have physical quantities with direction and magnitude that are not vectors?
• The radius of a circle is given as 2.12 cm. How can its area be represented?
(a) 14 cm2 (b) 14.1 cm2 (c) 14.11 cm2 (d) 14.1124 cm2.
