Q.The length of the chord of the parabola y² = 4ax parallel to y = mx + c is

\dfrac{4a \sqrt{1 + m^2}}{m^2}

\dfrac{2a \sqrt{1 + m^2}}{m^2}

\dfrac{4a}{m^2 \sqrt{1 + m^2}}

\dfrac{2a}{m^2 \sqrt{1 + m^2}}

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