Please solve RD Sharma class 12 chapter The Plane exercise 28.4 question 9 maths textbook solution
Answer:
Hint:
You must know the rules of solving vector functions
Given:
Find the equation of plane passing through (1,2,1) and perpendicular to the line joining the points (1,4,2) and (2,3,5). Find perpendicular distance.
Solution:
We have
The normal is passing through the points A(1,4,2) and B(2,3,5)
We know that the vector equation of the plane passing through a point (1,2,1)()
and normal to is
Putting
To find the perpendicular distance of this plane from this origin,
we have
Divide equation (1) by
The perpendicular distance of this plane from this origin
from equation (1)
