Two conductors A and B of the same material have their lengths in the ratio \(1: 2\) and radii in the ratio \(2: 3\) . If they are connected in parallel across a battery, the ratio \(\frac{v_{{A}}}{v_{{B}}}\) of the drift velocities of electrons in them will be-
- 2
- \(\frac{1}{2}\)
- \(\frac{3}{2}\)
- \(\frac{8}{9}\)
Answer
