Explain Solution R.D.Sharma Class 12 Chapter 28 The Plane Exercise 28.13 Question 16 Sub Question 2 Maths Textbook Solution.

Answers (1)

$2\left(4-\lambda^{2}\right)-0\left(2-\lambda^{2}\right)-2\left(\lambda^{2}-2\right)=0$

$8-2 \lambda^{2}-2 \lambda^{2}+4=0$

$\lambda^{2}+\lambda^{2}-6=0$

Let $\lambda^{2}=t$ then

$(t+3)(t-2)=0$

Put value of t

$\left(\lambda^{2}+3\right)\left(\lambda^{2}-2\right)=0$ is neglected because direction cosine cannot be imaginary

$\lambda^{2}=-3$

$Therefore, \lambda=\pm \sqrt{2}$
