Question

Column - I  Column - II   A) The eccentricity of the ellipse which meets the straight line 2x -3 y = 6 on the X-axis and the straight 1 line 4x + 5y= 20 on the Y-axis and whose principal axes lie along the coordinate axes, is  p) 1/2B) A bar of length 20 units moves with its ends on two fixed straight lines at right angles. A point P marked on the bar at  a distance of 8 units from one end describes a conic whose  eccentricity is  q) 1/√2 C) If one extremity of the minor axis of the ellipse x^2/a^2+y^2/b^2 = 1and the foci form an equilateral triangle , then its eccentricity is r) √5/3 D) There are exactly two points on the ellipse x^2/a^2+y^2/b^2 = 1 whose distance from the centre of the ellipse are greatest and equals to √{{a^2+2b^2}/2} Eccentricity of this ellipse is equal to  s) √7/4
