Question : 12 of 54

Marks: +1, -0

A particle of mass 6.6×10−30kg starts (t=0) moving on a straight line with velocity 10m∕s. Its velocity decreases with time, however rate of change of de-Broglie wavelength associated with particle remainsconstant at 10−4m∕s. (take h=6.6×10−34J−s) :

Velocity of particle at t=0.9s is m∕s
Velocity of particle at t=0.9s is 6m∕s
Magnitude of retardation of particle at t=0.9s is 4m∕s2
Magnitude of retardation of particle at t=0.9s is 1m∕s
