The maximum particle velocity is 3 times the wave velocity of a progressive wave.  If the amplitude of the particle is "a".  The phase difference between the two particles separated by a distance of 'x' is

a
xa
b
3xa
c
3ax
d
3πxa

detailed solution

Correct option is B

Maximum particle velocity v=aω Wave velocity = fλ Particle velocity = 3 (wave velocity)a.2πf=3fλ λ=2πa3 Phase difference = 2πλ  (Path difference)=2π2πa3(x) =3xa
