Question

A cable is cut into two equal parts. How will it affect the extension of the wire under same stretching force?​

Answer 1

I think that is 1 mili meter

Answer 2

When a cable is cut into two equal parts the effect of the extension of the wire under the same stretching force will be equal and the same.

• When the cable is cut into two equal parts, the length of the cable will become less than the actual length that is it will decrease. The area will not be affected.
• If we take into consideration Young's Modulus of rigidity of the wire, it will not change on cutting the wire because Young's Modulus is the physical property of a material.
• The same stretching force will let the extension and the length of the cable independent that is both will not be affected. Therefore, the effect of extension under the same stretching force will be the same.
