1.Which one of the following is correct? The eccentricity of the conic x2a2+λb2+y2b2+λb2=1\frac{x^2}{a^2 + \lambda b^2} + \frac{y^2}{b^2 + \lambda b^2} = 1a2+λb2x2+b2+λb2y2=1, (λb2≥0)(\lambda b^2 \geq 0)(λb2≥0)a.increases with increase in λ\lambdaλb.decreases with increase in λ\lambdaλc.does not change with λ\lambdaλd.None of the aboveLogin to continueOnly logged in users canattempt or see the solution.
