In this video, we solve a high-quality 3D Coordinate Geometry problem based on direction ratios and distance of a point from a line.
🔹 Given:
A line L passes through the point (−3, 5, 2)
Line makes equal angles with the positive coordinate axes
Distance of line L from the point (−2, r, 1) is sqrt( 14/3)
🔹 Task:
➡️ Find the sum of all possible values of r
📌 Concepts used:
Direction cosines of a line equally inclined to axes
Formula for distance of a point from a line in 3D
Handling multiple solutions logically
🎯 Best suited for:
JEE Main & JEE Advanced
Class 12 3D Geometry
Students preparing for objective + integer type questions
👉 Watch till the end for a shortcut-based and conceptual solution.
