Question

calculate the velocity of the particle of mass 0.1 MG which is associated with a wavelength of 3.3 into 10 raise to the power - 29 meter

Answer 1

Given conditions ⇒

Mass of the Particles = 0.1 Mg.
 = 0.1 × 10⁶ g.
 = 10⁵ g.

Wavelength of the Particles = 3.3 × 10⁻²⁹ m.

Using the de-broglie relation,

 λ = h/mv.
h = 6.62 × 10⁻³⁴ J-s. 

3.3 × 10⁻²⁹ = 6.62 × 10⁻³⁴/(10⁵ × v)
3.3 × 10⁻²⁴ × v = 6.62 × 10⁻³⁴
∴ v = 2.006 × 10⁻¹⁰ m/s. 


Hence, the velocity of the Particles is 2.006 × 10⁻¹⁰ m/s.
