Physics · Waves
The equation of a transverse wave propagating along a stretched string of length 80 cm is y = 1.5 sin(5 × 10-3 x + 20t), where 'x' and 'y' are in cm and time 't' is in seconds. If the mass of the string is 3 g, then the tension in the string is:
- 18 N
- 26 N✓
- 34 N
- 412 N
Correct answer
6 N
