JEE Main 2021 — Circle Question with Solution
From: JEE Main 2021 (Online) 18th March Morning Shift
Question
For the four circles M, N, O and P, following four equations are given :
Circle M : x2 + y2 = 1
Circle N : x2 + y2 2x = 0
Circle O : x2 + y2 2x 2y + 1 = 0
Circle P : x2 + y2 2y = 0
If the centre of circle M is joined with centre of the circle N, further center of circle N is joined with centre of the circle O, centre of circle O is joined with the centre of circle P and lastly, centre of circle P is joined with centre of circle M, then these lines form the sides of a :
Circle M : x2 + y2 = 1
Circle N : x2 + y2 2x = 0
Circle O : x2 + y2 2x 2y + 1 = 0
Circle P : x2 + y2 2y = 0
If the centre of circle M is joined with centre of the circle N, further center of circle N is joined with centre of the circle O, centre of circle O is joined with the centre of circle P and lastly, centre of circle P is joined with centre of circle M, then these lines form the sides of a :
