RBSE Maths Chapter 13: Exercise 13.2 Textbook Important Questions and Solutions
Question 1: If the magnitude of two vectors is 4 and 5, then find their scalar product if the angle between the two vectors is:
(i) 60° (ii) 90°
Solution:
If
\(\begin{array}{l}\vec{a}\end{array} \)
and
\(\begin{array}{l}\vec{b}\end{array} \)
be the two vectors and θ be the angle between them, then
