Answer:
1.2826 x 10^-13 m
Explanation:

Here, k be the kinetic energy and m be the mass
K = 50 KeV = 50 x 1.6 x 10^-16 J = 80 x 10^-16 J
m = 1.67 x 10^-27 kg

λ = 1.2826 x 10^-13 m
Answer:
what?
Explanation:
does that means also i learned Ratios and multiplication i keared them like 5 years ago?
Answer:
of its <u>mass</u> and its <u>acceleration</u>
<u>Explanation:</u>
based on Newton's second law of motion
Answer:
Wavelength, 
Explanation:
Given that,
Mass of the particle, 
Acceleration of the particle, 
Time, t = 5 s
It starts from rest, u = 0
The De Broglie wavelength is given by :

v = a × t



Hence, this is the required solution.
