A. The pulse will travel with increasing speed
B. The pulse will travel with uniform speed
C. The pulse will travel with decreasing speed
D. The pulse cannot travel through the rope
Answer:- A. The pulse will travel with increasing speed
The right option is A. The pulse will travel with cumulative speed
The tension in the rope will be increasing along the rope from the lower end to the upper end. The speediness of wave pulse is specified as,
v=√Tμ
Where T→Tension in string and μ→linear mass density of the rope.
⇒Since, T↑ as wave pulse travels up the rope, hence its speed will keep on increasing.
