Two wires of same material , having cross-sectional areas in the ratio 1 : 2 and lengths in the ratio 1 : 4 are stretched by the same force. The ratio of the stresses in the wires will be ………….. .

A

`1 : 2`

B

`2 : 1`

C

`1 : 4`

D

`4 : 1`

Text Solution

Verified by Experts

The correct Answer is:
B

Stress = `F/A , (("Stress")_1)/(("Stress")_2) = (A_2)/(A_1) = 2/1`
