JEE Math Practice Question
The straight line x + 2y = 1 meets the coordinate axes at A and B. A circle is drawn through A, B and the origin. Then the sum of perpendicular distances from A and B on the tangent to the circle at the origin is :
- A.$$4\sqrt 5 $$
- B.$${{\sqrt 5 } \over 2}$$
- C.$$2\sqrt 5 $$
- D.$${{\sqrt 5 } \over 4}$$
