Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

The friends now try a homework problem.
Consider an electron, of charge magnitude e = 1.602 × 10-¹⁹ C and mass me = 9.11 x 10-31 kg, moving in an elect
field with an electric field magnitude E = 7 x 10² N/C, similar to what Thana observed in the simulation. Let the leng
the plates be L = 50 cm, and the distance between them be d = 20 cm. Find the maximum speed, v, the electron co
be moving if it enters the space halfway between and parallel to the two plates to just barely strike one of the plates
7.01e+06 X m/s
If the field is pointing upward, which plate will Thana conclude the electron strikes at this speed?
The lower plate, because the electron is negatively charged.
The lower plate, because the electron is attracted to the negative plate.
The upper plate, because we are only considering the magnitude of the electron charge, and magnitudes are
always positive.
O
The upper plate, because the electron charge magnitude is positive.
