The centre of a circle C is at the centre of the ellipse E:\ \dfracx^2a^2+\dfracy^2b^2=1,\ a>b. Let C pass through the foci F_1 and F_2 of E such that the circle C and the ellipse E intersect at four points. Let P be one of these four points. If the area of the triangle PF_1F_2 is 30 and the leng... | Watch the step-by-step video solution for this NIMCET PYQ.
