EXERCISE 29.10

Q1.

Solution:

Let P(x1, y1, z1) be any point on plane 2x – y + 3z – 4 = 0.

⟹ 2x1 – y1 + 3z1 = 4 …….. (1)

Distance between (x1, y1, z1) and the plane

6x – 3y + 9z + 13 = 0:

We know, the distance of point (x1, y1, z1) from the plane π: ax + by + cz + d = 0 is given by: Q2.

Solution:

Since the plane is parallel to 2x – 3y + 5z + 7 = 0, it must be of the form:

2x – 3y + 5z + θ = 0

It is given that,

The plane passes through (3, 4, –1)

⟹ 2(3) – 3(4) +5(–1) + θ = 0

θ = -11

So, the equation of the plane is as follows:

2x – 3y + 5z – 11 = 0

Distance of the plane 2x – 3y + 5z + 7 = 0 from (3, 4, –1):

We know, the distance of point (x1, y1, z1) from the plane π: ax + by + cz + d = 0 is given by: Q3.

Solution:

Given:

Equation of planes: π1= 2x – 2y + z + 3 = 0

π2= 2x – 2y + z + 9 = 0

Let the equation of the plane mid–parallel to these planes be:

π3: 2x – 2y + z + θ = 0

Now,

Let P(x1, y1, z1) be any point on this plane,

⟹ 2(x1) – 2(y1) + (z1) + θ = 0 …… (1)

We know, the distance of point (x1, y1, z1) from the plane π: ax + by + cz + d = 0 is given by:  Q4.

Solution:
