A) \[\frac{15{{a}^{3}}}{4}\]sq units
B) \[\frac{15{{a}^{2}}}{4}\]sq units
C) \[\frac{7{{a}^{2}}}{4}\]sq units
D) \[\frac{{{a}^{2}}}{4}\]sq units
Correct Answer: B
Solution :
Equation of any tangent of the parabola,\[{{y}^{2}}=4ax\]is\[y=mx+\frac{a}{m}\]. This line will touch the circle\[{{x}^{2}}+{{y}^{2}}=\frac{{{a}^{2}}}{2}\].You need to login to perform this action.
