Answer:
Yes the statement is correct
Explanation:
The de-broglie relation is mathematically represented as
where
p is momentum of the system
From the relation we can see that the wavelength is inversely proportional to the momentum of the particle.

Answer:
a) 2.3 x 10⁴ m/s
b) 4.42 x 10⁻¹⁹ J or 2.8 eV
Explanation:
θ = Angle between the direction of motion of proton and magnetic field = 35
B = magnitude of magnetic field = 0.026 T
F = magnitude of magnetic force =5.5 x 10⁻¹⁷ N
q = magnitude of charge on proton = 1.6 x 10⁻¹⁹ C
v = speed of proton
magnetic force on proton is given as
F = q v B Sinθ
5.5 x 10⁻¹⁷ = (1.6 x 10⁻¹⁹) (0.026) Sin35 v
v = 2.3 x 10⁴ m/s
b)
m = mass of the proton = 1.67 x 10⁻²⁷ kg
Kinetic energy of proton is given as
KE = (0.5) m v²
KE = (0.5) (1.67 x 10⁻²⁷) (2.3 x 10⁴)²
KE = 4.42 x 10⁻¹⁹ J
we also know that, 1 eV = 1.6 x 10⁻¹⁹ J
KE =
KE = 2.8 eV
