A force F is applied on the wire of radius `r` and length L and change in the length of wire is `l`. If the same force F is applied on the wire of the same material and radius 2r and length 2L. Then the change in length of the other wire is

A wire of length L and radius r is clamped rigidly at one end. When the other end of the wire is pulled by a force f its length increases by l. Another wire of the same material of length 2L and radius 2r is pulled by a force 2f. Then find the increase in length of this wire.

A force F is required to break a wire of length L and radius r. Find the force required to break a wire of the same material, length 2L and radius 4r.

Two wires of same diameter of the same material having the length l and 2l If the force F is applied on each, the ratio of the work done in two wires will be

Two wires of same diameter of the same material having the length l and 2l If the force F is applied on each, the ratio of the work done in two wires will be

Two wires of same diameter of the same material having the length l and 2l If the force F is applied on each, the ratio of the work done in two wires will be

A wire of length L and radius r is clalmped rigidly at one end. When the other end of the wire is pulled by force f, its length increaes by l. Another wire of the same material of length 2 L and radius 2 r, is pulled by a force 2 f. Find the increase in length of this wire.

Two wires of same diameter of the same material having the length l and 2l .If the force F is applied on each, the ratio of the work done in the two wires will be

The resistance of a wire of uniform diameter d and length L is R . The resistance of another wire of the same material but diameter 2d and length 4L will be

On applying the load the increment in length of a wire is 1 mm. On applying the same load on another wire of same length and material, but having half the radius, the increment will be
