Consider the situation shown in figure. The force F is equal to mg. If area of cross-section of the string is A and its Young's modulus is Y, the strain developed in the wire is (the string is light and there is no friction anywhere)
Options:
Answer:
C
Solution:
The accelerating mass gives string tension mg/2.
Hence strain is mg/(2AY).
