If the de-broglie wavelength of a particle of mass (m) is 100 times its velocity. Then, its value in terms of its mass (m) and plank constant (h) is

Question

Quantrex Academy · Accepted Answer

Correct answer: B. 10 h m

Let the wavelength of given particle =x Velocity (v)= x 100 Using wavelength formula aligned = h m v \ & x = h m ( x 100 ) \ x & = 100 h m x \ x^2 & =100 h m \ x & =10 h m aligned
