A) \[x=1\]
B) \[2x+1=0\]
C) \[x=1\]
D) \[2x1=0\]
Correct Answer: C
Solution :
\[{{y}^{2}}=4x\] comparing with \[{{y}^{2}}=4ax\] \[a=1\] Locus of point P will be directrix of given parabola as tangents drawn from P are at right angles, therefore required locus is \[x=a\] \[x=1\]You need to login to perform this action.
