Calculate the force acting on an electron of charge 1.5 x 10-19C placed in an electric field of intensity 105Vm-1

Answer Details

The force acting on an electron in an electric field can be calculated using the formula F = qE, where F is the force, q is the charge of the electron, and E is the electric field intensity. So, in this case, the force acting on an electron of charge 1.5 x 10^-19 C placed in an electric field of intensity 10^5 V/m can be calculated as: F = qE = 1.5 x 10^-19 C * 10^5 V/m = 1.5 x 10^-14 N Therefore, the force acting on the electron is 1.5 x 10^-14 N, which is closest to the option 1.5x10-14N.
