A proton moves with a speed of 0.88c. Find the speed of an
electron that has the same momentum and kinetic energy. (Express
the answer as the quantity of one minus a number times c.)

A proton has 1836 times the rest mass of an electron. At what
speed will an electron have the same momentum as a proton moving at
0.0087 c?

An electron has a kinetic energy K of 1 MeV and is incident on a
proton at rest in the laboratory. Calculate the speed of the CMS
frame (The centre of mass, or centre of momentum, (CMS) frame is
that in which the sum of the momenta (i.e., the total momentum) of
all particles is zero) moving relative to the laboratory.
(a) Express the initial energies Ee, Ep and initial momenta pe,
pp of the electron and proton respectively (with...

(A) At what speed (in m/s) will a proton move in a circular path
of the same radius as an electron that travels at 7.10 ✕ 106 m/s
perpendicular to the Earth's magnetic field at an altitude where
the field strength is 1.10 ✕ 10−5 T?
(B) What would the radius (in m) of the path be if the proton
had the same speed as the electron?
(C) What would the radius (in m) be if the proton had the...

(a) At what speed (in m/s) will a proton move in a circular path
of the same radius as an electron that travels at 7.00 ✕ 10^6 m/s
perpendicular to the Earth's magnetic field at an altitude where
the field strength is 1.05 ✕ 10^−5 T? (b) What would the radius (in
m) of the path be if the proton had the same speed as the electron?
(c) What would the radius (in m) be if the proton had the...

Proton has 1836 times the rest mass of an electron. With this
information, calculate the speed the electron will have the
equivalent amount of momentum as a proton moving at 0.0011c?
Velocity = _______ c

The hydrogen atom consists of one electron orbiting one proton
in a circular orbit.
(a) Using Coulomb's Law and concepts of
centripetal acceleration/force, show that the radius
r of the orbit is given by
where K is the kinetic energy of the electron,
k is the Coulomb's Law constant, +e is the charge
of the proton, and -e is the charge of the electron.
(b) Calculate r when the
kinetic energy of the electron is 13.6 eV.
(c) What percentage...
