Question

If the length of a wire is made double and the radius is halved of its respective values. Then, Young's modules of the material of the wire will ______.

विकल्प

• Remain the same

• Become 8 times its initial value

• Become 1/4^th of its initial value

• Become 4 times its initial value

Answer 1

If the length of a wire is made double and the radius is halved of its respective values. Then, Young's modules of the material of the wire will remain the same.

Explanation:

Young modulus is determined by the wire's substance rather than its length and cross-section area.
