Understanding the Plane Equation
The equation of the plane given is z = 2. This indicates that the plane is parallel to the x-y plane and is located at a height of 2 units above it.
Normal Vector to the Plane
- The normal vector to a plane defined by the equation Ax + By + Cz + D = 0 can be derived from the coefficients A, B, and C.
- For the plane z = 2, we can rewrite it as 0x + 0y + 1z - 2 = 0.
- Here, A = 0, B = 0, C = 1.
Direction Cosines
- The direction cosines of a normal vector (n_x, n_y, n_z) are given by the ratios of the components of the normal vector to its magnitude.
- For our normal vector (0, 0, 1), the magnitude is √(0² + 0² + 1²) = 1.
- Therefore, the direction cosines are:
- n_x = 0/1 = 0
- n_y = 0/1 = 0
- n_z = 1/1 = 1
Distance from the Origin
- The distance d from the origin (0, 0, 0) to the plane z = 2 can be calculated as the absolute value of the constant term divided by the magnitude of the normal vector.
- Here, d = |D| / √(A² + B² + C²) = |2| / 1 = 2.
Conclusion
- The direction cosines of the normal to the plane z = 2 are (0, 0, 1), and the distance from the origin to the plane is 2.
- Hence, the correct answer is option 'D': (0, 0, 1).
