Find the vector equation of the plane passing through the point (a, b, b) and parallel to the plane
There is a error in question …… the point should be (a,b,c) instead of (a,b,b) to get the required answer.
Formula : Plane = r . (n) = d
Where r = any random point
n = normal vector of plane
d = distance of plane from origin
If two planes are parallel , then their normal vectors are same.
Therefore ,
Parallel Plane r . (i + j + k) = 2
Normal vector = (i + j + k)
∴ Normal vector of required plane = (i + j + k)
Equation of required plane r . (i + j + k) = d
In cartesian form x + y + z = d
Plane passes through point (a,b,c) therefore it will satisfy it.
(a) + (b) + (c) = d
d = a + b + c
Equation of required plane r . (i + j + k) = a + b + c
