JEE Advanced Paper I problem based on 3 D Geometry (Hindi)
This video covers the problem of 3-dimensional geometry taken from recently held JEE Advanced 2020 Paper I question 11 and the question is
Let L1 and L2 be the following straight lines L1 : (x – 1)/1 = y/(−1) = (z – 1)/3 and L2 : (x – 1)/(−3) = y/(−1) = (z – 1)/1. Suppose the straight line lies in the plane containing L1 and L2, and passes through the point of intersection of L1 and L2. If the line L bisects the acute angle between the lines L1 and L2, then which of the following statements is/are TRUE? (A) α − γ = 3 (B) l + m = 2 (C) α − γ = 1 (D) l + m = 0
This video is suitable for the students aspiring for engineering entrance exam and is also suitable for CBSE, ISC, HSC Board students and the students who have genuine interest in learning geometry
