The foci of an ellipse are `S(3,1)` and `S'(11,5)`The normal at P is `x+2y-15=0` Then point P is

Foci of an ellipse are at S(1,7),S'(1,-3) .The point P is on the ellipse such that SP=7,S'P=5 .then the equation of the ellipse is

Foci of an ellipse are at S(l,7),S'(l,-3) - The point P is on the ellipse such that SP = 7, S'P = 5. Then the equation of the ellipse is

S_1a n dS_2 are the foci of an ellipse of major axis of length 10 units, and P is any point on the ellipse such that the perimeter of triangle P S_1 is 15. Then the eccentricity of the ellipse is 0.5 (b) 0.25 (c) 0.28 (d) 0.75

S_(1),S_(2), are foci of an ellipse of major axis of length 10 units and P is any point on the ellipse such that perimeter of triangle PS_(1)S_(2) is 15. Then eccentricity of the ellipse is:

S_1, S_2 , are foci of an ellipse of major axis of length 10 units and P is any point on the ellipse such that perimeter of triangle PS_1 S_2 , is 15 . Then eccentricity of the ellipse is:

S_1, S_2 , are foci of an ellipse of major axis of length 10 units and P is any point on the ellipse such that perimeter of triangle PS_1 S_2 , is 15 . Then eccentricity of the ellipse is:

S_1, S_2 , are foci of an ellipse of major axis of length 10 units and P is any point on the ellipse such that perimeter of triangle PS_1 S_2 , is 15 . Then eccentricity of the ellipse is:

Let S and S^(1) be the foci of an ellipse . At any point P on the ellipse if SPS^(1) lt 90 ^(@) then its eccentricity :
