The sum of the intercepts made on the axes of coordinates by any tangent to the curve

\sqrt{x}+\sqrt{y}=\sqrt{a}

is equal to

View answer and explanation

Correct option: B

a

Option B (

a

) is correct because the sum of the intercepts is equal to

\sqrt{a}(\sqrt{x_1} + \sqrt{y_1})

, which simplifies to

a

using the equation of the curve.
