JEE Advanced 2020 Paper 2 Problem on Circle (Hindi)
This video covers a very interesting problem on “Circle” with lot of use of geometry and covers the concept of properties of distance of point and a line, circumcenter of triangle, distance between parallel line taken from recently held JEE Advanced 2020 Paper II question number 1 and the question is
Let O be the centre of the circle x^2 + y^2 = r^2, where r √5/2. Suppose PQ is a chord of this circle and the equation of the line passing through P and Q is 2x + 4y = 5. If the centre of the circumcircle of the triangle OPQ lies on the line x + 2y = 4, then the value of r is _____
This video is suitable for the students aspiring for engineering entrance exam and is also suitable for CBSE, ISC, HSC, IB Board students and the students who have genuine interest in learning geometry
