What will be the value of elasticity of demand (eₑ) if the demand curve has a shape of rectangular hyperbola?
\(\left|e_D\right|\) = 1
\(\left|e_D\right|\)= Above 0 but less than 1
\(\left|e_D\right|\)= 0
\(\left|e_D\right|\) = Always remains above 1
If P, F and C represent the pole, principal focus and centre of curvature, respectively, of a concave mirror, then PC is equal to:
Two resistors, A of 10 Ω and B of 20 Ω, are connected in series with a battery of 6 V. If V₁ and V₂ are the potential drops across A and B and I₁ and I₂ are the currents through them, respectively, then (V₁:V₂) and (I₁:I₂) are respectively
\( \frac{1}{2} \) and \( \frac{1}{2} \)
2 and \( \frac{1}{2} \)
\( \frac{1}{2} \) and 1
2 and 1
