Answer & Solution

Correct Answer

(C) \(\frac{\pi}{2}\)

Step-by-step Solution

Detailed explanation

Given equation of line is \(\begin{aligned} 3 x+4 y-5 & =0 \\ \frac{3 x+4 y}{5} & =1 \quad \ldots (i) \end{aligned}\) Equation of curve is \(2 x^2+3 y^2=5\) ...(ii) Homogenising Eq. (ii) using Eq. (i)…
