A tower stands at the centre of a circular park. A and B are two points on the boundary of the park such that `A B""(=""a)` subtends an angle of `60o` at the foot of the tower, and the angle of elevation of the top of the tower from A or B is `30o` . The height of the tower is (1) `(2a)/(sqrt(3))` (2) `2asqrt(3)` (3) `a/(sqrt(3))` (4) `asqrt(3)`

A

`2a//sqrt(3)`

B

`2a sqrt(3)`

C

`a// sqrt(3)`

D

`a sqrt(3)`
