JEE MainPhysicsModerateWave on a string
A non−uniform string of mass 45 kg and length 1.5 m has a
variable linear mass density given by μ = kx, where x is the distance
from one end of the string and k is a constant. Tension in the string is
15 N which is uniform. If the time (in second) required for a pulse
generated at one end of the string to travel to the other end is x, then
find the value of 2x.
