## NCERT Solutions for Class 12 Maths Chapter 10 Vector Algebra (Ex 10.3) Exercise 10.3

## FAQs on NCERT Solutions for Class 12 Maths Chapter 10 - Exercise

**1. What is the main concept given in Class 12 Maths Exercise 10.3?**

It is primarily based on the scalar product of two vectors. It is possible to define the dot product as the product of the magnitudes of the two vectors and the angle between the two vectors' cosine values. Another definition is the product of a first-to-second projection and magnitude of the second vector. This exercise deals with different problems related to the dot product of 2 vectors.

**2. Which is the most important question from Exercise 10.3 of Class 12 Maths?**

There is no such thing as the most important question! As you can see, the simpler ones help you remember your ideas, whilst the more difficult ones test your problem-solving abilities and how well you can indicate your principles in practical situations. You must pay close attention to Chapter 10. Refer to all problems in NCERT Class 12 Maths Chapter 10.

**3. What is the dot product of 2 Vectors?**

This number (Scalar quantity) is generated by executing an operation on the vector components and it is termed the dot product or scalar product. Only vectors with the same number of dimensions can be combined using the dot product. The dot product has a heavy dot as its logo. It is a very crucial topic and must be learned well as it has multiple applications across domains of Math and Physics.

**4. Is dot Product Scalar Class 12?**

Often referred to as the Scalar Product, the Dot Product returns a Scalar (Normal Number) response. On the other hand, there's also the Cross Product, which delivers the solution as a Vector. Both are equally crucial and have their own significance in Math and Physics. Learn both the topics well with clear knowledge of their fundamentals and also practice the related exercises.

**5. Is Cross Product Vector Class 12?**

Using the right-hand thumb rule, you may calculate its magnitude by measuring the area of the parallelogram between them. When two vectors are crossed, the outcome of that cross is called a vector quantity. Hence yes, the cross product of any two vectors yields another vector as the answer. Practice the different problems as much as you can.
