A) \[\left( \frac{a}{{{m}^{2}}},\frac{-2a}{m} \right)\]
B) \[\left( \frac{a}{{{m}^{2}}},\frac{2a}{m} \right)\]
C) \[(a{{m}^{2}},2am)\]
D) None of these
Correct Answer: B
Solution :
Given, line \[y=\operatorname{mx}+\frac{a}{m}\] ... (i) and parabola \[{{y}^{2}}=4ax\] ... (ii) On solving Eqs. (i) and (ii), we get Point of contact \[=\left( \frac{a}{{{m}^{2}}}.\frac{2a}{m} \right)\]
