MHT CET 2026 Physics question
A wire is under tension of 2 kg wt and a wave is travelling through it with some speed. Tension in the wire is so increased that the wave travels through it with thrice the original speed. The increase in tension is (in kg wt)
Answer: (C)
Solution
The speed of a transverse wave on a stretched wire is , so for the same wire. If the speed becomes , then kg wt. The increase in tension is kg wt, option (C).
