JEE Main 2026 Physics question

The two wires A and B of equal cross-section but of different materials are joined together. The ratio of Young's modulus of wire A and wire B is 20/11. When the joined wire is kept under certain tension the elongations in the wires A and B are equal. If the length of wire A is 2.2 m, then the length of wire B is m.

• (A)1.1
• (B)2.22
• (C)1.21Correct
• (D)4.44
