At what speed (in m/s) will a proton move in a circular path of the same radius as an electron that travels at 7.45 ✕ 106 m/s perpendicular to the Earth's magnetic field at an altitude where the field strength is 1.10 ✕ 10−5 T

The speed of the proton is 4059.39 m/s

Explanation:

The centripetal force on the particle is given by;

The magnetic force on the particle is given by;

The centripetal force on the particle must equal the magnetic force on the particle, for the particle to remain in the circular path.

where;

r is the radius of the circular path moved by both electron and proton;

⇒For electron;

⇒For proton

The speed of the proton is given by;

Therefore, the speed of the proton is 4059.39 m/s

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

this is poiselle's equation from fluid mechanic in physics. mech eng
