The length of conjugate axis of a hyperbola is greater than the length of transverse axis. Then, the eccentricity e is

Options

  1. A= 2
  2. B> 2
  3. C< 2
  4. D< 1 2

Correct answer

B. > 2

Step-by-step solution

Let the length of conjugate axis =b and the length of transvers axis =a Given that, b>a Now, b²>a² Eccentricity (e)= 1+ b² a² e²= ( 1+ b² a² )²>2e> 2
