Need solution for RD Sharma maths class 12 chapter 28 The Plane exercise multiple choice question 19

Answers (1)

Answer:

Option (d)

Hint:

Solve the equation to get the values of x, y and z

Given:

xy + yz = 0

Solution:

We have

xy + yz = 0

x (y + z) = 0

therefore x = 0, y + z = 0

Above one equation of planes normal to the plane x = 0 is $\widehat{i}$

y + z = 0 is

$\widehat{j}+\widehat{k},$

And normal to the plane

$\widehat{i}.(\widehat{j}+\widehat{k})=0$

So, planes are perpendicular.
