QJEEM23Ph88bd: JEE Main 2023 Physics - Class 11 JEEM23Ph88bd Solution: A steel wire with mass per unit length 7.0 × 10 − 3   kg…

A steel wire with mass per unit length 7.0×10−3 kg m−1 is under tension of 70 N. The speed of transverse waves in the wire will be:

Multiple Choice Options

  • A 10 m/s
  • B 50 m/s
  • C 100 m/s
  • D 200π m/s

Step-by-Step Verified Solution

Speed of transverse wave =Tμ=\sqrt{\frac{T}{\mu}} =707×10−3=100 m/s=\sqrt{\frac{70}{7 \times 10^{-3}}}=100 \mathrm{~m} / \mathrm{s}
