The eccentricity of an ellipse whose centre is at the origin is `1/2`. If one of its directrices is x = - 4, then the equation of the normal to it at (1, 3) is :

The eccentricity of an ellipse whose centre is at the origin is 1/2 . If one of its directrices is x = - 4, then the equation of the normal to it at (1, 3/2) is :

The eccentricity of an ellipse whose centre is at the origin is 1/2 . If one of its directrices is x = - 4, then the equation of the normal to it at (1, 3/2) is :

The eccentricity of an ellipse whose centre is at the origin is 1/2dot if one of its directrices is x=-4, then the equation of the normal to it at (1,3/2) is:

The eccentricity of an ellipse whose centre is at the origin is 1/2dot if one of its directrices is x=-4, then the equation of the normal to it at (1,3/2) is: (1) 4x+2y=7 (2) x+2y=4 (3) 2y-x=2 (4) 4x-2y=1

The eccentricity of an ellipse whose centre is at the origin is (1)/(2) .if one of its directrices is x=-4, then the equation of the normal to it at (1,(3)/(2)) is: 4x+2y=7(2)x+2y=4(3)2y-x=2(4)4x-2y=1

The eccentricity of an ellipse, with its centre at the origin, is 1/2. If one of the directrices is x = 4, then the equation of the ellipse is
