A brass wire of length 300 cm when subjected to a force F produces an elongation "a". Another wire of twice the diameter and of same length and material, when subjected to the force F produces an elongation b. Then the value of .a/b. is

A brass wire of length 300cm when subjected to a force F produces an elongation "a" . Another wire of twice the diameter and of same length and material, when subjeceted to the force F produces and elongation b . Then the value of a//b is

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.

The extension of a wire by the application of a load is 2 mm. The extension in a wire of the same material and same length but half the radius by the same load is
