Auniform 4.4 t magnetic field points north. if an electron moves vertically downward (toward the ground) with a speed of 2.5 × 107 m/s through this field. the charge on a proton is 1.60×10−19 .
a. what is the magnitude of the force acting on it? answer in units of n.
The force acting on the electron due to the magnetic field is
is the charge of the electron
is its speed
is the intensity of the magnetic field
is the angle between the direction of the field and the velocity of the electron
Substituting all the numbers into the equation, we find
when it gains or loses electrons
they should be similar or the same
