Question

Two wires of the same radius and material have their length in the ratio 1 : 2. If these are stretched by same force and strain produced in the two wires will be in the ratio –

• A. 1 : 1
• B. 1 : 2
• C. 2 : 1
• D. 1 : 4

Answer 1

Answer: (A)

1 : 1

Answer 2

A = constt.

Y = constt.

L₁ : L₂ : : 1 : 2

F = constt.

Y = $\frac{Stress}{Strain}$

\ Strain = constt.
