Let the length of the focal chord PQ of the parabola y^2=12 x be 15 units. If the distance of PQ from the origin is p , then 10 p ^2 is equal to _______
Correct answer
0
Step-by-step solution
aligned & length of focal chord =4 a cosec ^2 =15 & 12 cosec ^2 =15 & ^2 = 4 5 & ^2 =4 & =2 & equation y-0 x-3 =2 & y=2 x-6 & 2 x-y-6=0 & P= 6 5 & 10 p^2=10 36 5 =72 aligned
