# NCERT Solutions Class 12 Maths Chapter 10 Exercise 10.4 Vector Algebra

NCERT solutions for class 12 maths chapter 10 exercise 10.4 vector algebra introduces the confusing topic of cross-product that has found various applications in geometry, mechanics, and engineering. Cross-product is not very difficult to understand if studied with diligence. The only tricky part is determining the direction. For this, a right-handed screw would advance in the direction of the positive z-axis if we rotate the x-axis of a right-handed rectangular coordinate system counterclockwise into the positive y-axis. Thus, in this system the thumb of the right-hand points in the direction of the positive z-axis when the fingers are curled in the direction toward the positive y-axis away from the positive x-axis indicating the direction. NCERT solutions class 12 maths chapter 10 exercise 10.4 provides kids with well-crafted matter so as to build a deep-seated understanding of this topic.

Class 12 maths NCERT solutions chapter 10 exercise 10.4 vector algebra requires the concept of matrix multiplication so as to compute the cross-product of vectors. Hence, if students do not have a good understanding of this topic they should revisit it. This exercise has 12 sums curated in different formats ranging from moderate to difficult levels. The PDF solution given below to these problems will help students build an ironclad foundation so as to compute the cross-product of vectors.

## NCERT Solutions Class 12 Maths Chapter 10 Exercise 10.4 Formulas

NCERT solutions class 12 maths chapter 10 vector algebra gives the property of the distributivity of vector product over addition that helps kids perform calculations faster. If we have three vectors a, b, c, and a scalar λ then:

- a × (b + c) = a × b + a ×
- λ(a × b) = (λa) × b = a × (λb)

NCERT solutions class 12 maths chapter 10 exercise 10.4 must be practiced regularly as this concept can prove to be tricky. The only way to combat confusion is by applying the formulas and procedures to questions several times so as to build a deep-seated knowledge of the section.
