The temperature of a wire is doubled. The Young's modulus of elasticity

A

also double

B

become four times

C

remain same

D

decrease.

Text Solution

Verified by Experts

The correct Answer is:
D
As `Y = (FL)/(ADeltaL)`, when temperature is doubled , `DeltaL` increase, and accordingly Y decrease.
