Consider the set the of hyperbola `xy = k, k in R`. Let `e_(1)` be the eccentricity when `k = 4` and `e_(2)` be the eccentricity when `k = 9` then `e_(1) - e_(2) =`

A

`-1`

B

`0`

C

`2`

D

`3`

Text Solution

Verified by Experts

The correct Answer is:
B

`e_(1) = sqrt(2) , e_(2) = sqrt(2)`
`e_(1) = e_(2) = sqrt(2) - sqrt(2) = 0`
