Class 12 RD Sharma Textbook Solutions Chapter 25 - Vector or Cross Product

Consider a and b as two non-zero parallel vectors. The cross product of two vectors a and b is defined only in three-dimensional space and it is denoted by a×ba×b. The Vector is also known as Cross Product.

Vector Product is defined by the following formula:

$a \times b = \left | a \right | \left |b \right |\sin(\theta )n a \times b =  \left | a \right | \left |b \right |\sin(\theta )n$

Where |a||a| is the modulus of aa. It is also known as the magnitude of aa

$  \left |b \right | \left |b \right |$  is the modulus of bb

θθ is the angle between two vectors aa and bb, and nn is a unit vector


Following Are The Properties of Vector Product

  1. Vector product does not follow the commutative rule. It is given by 

 $a \times b = -(b \times a)a\times b = -(b \times a)$

  1. Vector multiplication rule

 $(ka) \times b = k(a \times b) = a \times(kb)(ka)\times b = k(a\times b) = a \times (kb)$

  1. If the given vectors are collinear then a×b=0a×b=0

(Since the angle between both the vectors would be 00, then the value of $\sin(0)=0\sin(0)=0$)

  1. a×ba×b in terms of unit vectors can be represented as

$a = a_1 \hat{i} + a_2 \hat{j} + a_3 \hat{j}a =  a_1 \hat{i} + a_2 \hat{j} + a_3 \hat{j}$  

$b = b_1 \hat{i} + b_2 \hat{j} + b_3 \hat{j}b =  b_1 \hat{i} + b_2 \hat{j} + b_3 \hat{j}$  

$a \times b = ( a_1 \hat{i} + a_2 \hat{j} + a_3 \hat{j})( b_1 \hat{i} + b_2 \hat{j} + b_3 \hat{j}) a \times b =  ( a_1 \hat{i} + a_2 \hat{j} + a_3 \hat{j})( b_1 \hat{i} + b_2 \hat{j} + b_3 \hat{j})$

  1. Vector product follows distributive laws

 $a \times (b + c) = (a \times b) + (a \times c) a \times (b +c) = (a \times b)+(a \times c)$
