Two wires of the same material but of different diameters carry the same current `i`. If the ratio of their diameters is `2:1` , then the corresponding ratio of their mean drift velocities will be

Two wires made of same material but of different diameters are connected in series in a circuit. The current flows in the combination of wires. When the current flows from the wire with larger diameter to the one with smaller diameter, what happens to the drift velocity of electrons ?

Two wires made of same material have lengths in the ratio 1:2 and their volumes in the same ratio. The ratio of their resistances is

Two wires of the same material have lengths in the ratio 1:2 and diameters in the ratio 2:1 . If they are stretched by the same force, the ratio of their expansion will be

Two wires of the same material and of the same diameter have their lengths in the ratio 1:3 and are under tension in the ratio 1:4 Compare their fundamental frequencies.

Two solid spheres are made of the same material. The ratio of their diameters is 2: 1. The ratio of their moments of inertia about their respective diameters is

Two wires of the same material but of lengths in the ratio 2:3 and diameters in the ratio of 3:2 are stretched with equal force. Then the ratio of elongations produced is
