The equation of a wave travelling on a string is y = [20 x +10 t ] , where x and t are distance and time in SI units. The minimum distance between two points having the same oscillating speed is :

Options

  1. A5.0 cm
  2. B20 cm
  3. C10 cm
  4. D2.5 cm

Correct answer

A. 5.0 cm

Step-by-step solution

Minimum distance between 2 points having same speed is 2 . = 2 k = 1 10 ~m =10 ~cm Distance = 2 =5 ~cm
