y=m x+6

is a tangent to the hyperbola

\frac{x^2}{100}-\frac{y^2}{49}=1

and the parabola

y^2=4 a x

, then the length of the latus rectum of the parabola is

View answer and explanation

Correct option: C

24 \sqrt{\frac{17}{20}}

Option C (

24 \sqrt{\frac{{17}}{{20}}}

) is correct because it involves finding the slope of the tangent to the hyperbola, then using that slope to find 'a' for the parabola and finally calculating the latus rectum.
