JEE Math Practice Question
A tower stands at the centre of a circular park. $$A$$ and $$B$$ are two points on the boundary of the park such that $$AB(=a)$$ subtends an angle of $${60^ \circ }$$ at the foot of the tower, and the angle of elevation of the top of the tower from $$A$$ or $$B$$ is $${30^ \circ }$$. The height of the tower is :
- A.$$a/\sqrt 3 $$
- B.$$a\sqrt 3 $$
- C.$$2a/\sqrt 3 $$
- D.$$2a\sqrt 3 $$
