Calculate the force acting on an electron of charge 1.6 x 10-19C placed in an electric field of intensity 108Vm-1
Answer Details
The force (F) acting on an electron in an electric field is given by the equation F = qE, where q is the charge of the electron and E is the electric field intensity.
Substituting the given values, we have:
F = (1.6 x 10^-19 C) x (10^8 V/m)
F = 1.6 x 10^-11 N
Therefore, the force acting on the electron is 1.6 x 10^-11 N, which is option (A).
Note that the force is very small due to the small charge of the electron and the relatively weak electric field intensity.
