Q.The equation of the ellipse with centre (0,0) and eccentricity 1/2 with major axis along x-axis and length 10 is

\dfrac{x^2}{25} + \dfrac{y^2}{100/4} = 1

\dfrac{x^2}{25} + \dfrac{y^2}{75/4} = 1

\dfrac{x^2}{100} + \dfrac{y^2}{75} = 1

\dfrac{x^2}{100} + \dfrac{y^2}{25} = 1

The correct solution involves applying the fundamental concept to derive the final value step by step...
