A normal is drawn to the parabola "y^(2)=9x" at the point "P(4,6)." A circle is described on "SP" as diameter; where "S" is the focus.The length of the intercept made by the circle on the normal at point "P" is: (A) "(17)/(4)," (B) "(15)/(4)," (C) "4," (D) "5
A= 9/4
4=at1^2
t1=4/3
Length of intercept =a(1+t1^2)^1/2
=15/4
