If the latus rectum of a hyperbola through one focus subtends an angle (60^ ) at the other focus, then its eccentricity is

Options

  1. A( 2 )
  2. B( 6 )
  3. C( 3 )
  4. D( 5 )

Correct answer

C. ( 3 )

Step-by-step solution

Given, latus rectum of one hyperbola subtends an angle of (60^ ) at other follows, From ( A B C ), ( array llll & 30^ = b^2 / a 2 a e & 1 3 = b^2 2 a^2 e & Also b^2 =a^2 (e^2-1 ) & So, 1 3 = a^2 (e^2-1 ) 2 a^2 e & 2 e = 3 (e^2-1 ) & e = 3 array )
