An electron is placed in a uniform electric field of 5 × 105 N/C that points to the right. (e = 1.6 × 10-19 C, melectron = 9.11 × 10-31 kg). What is the magnitude of the force on the electron?
Force on electron due to electric field is given by:
F = q*E
q = charge on electron = -1.6*10^-19 C
E = electric field = 5*10^5 N/C
So magnitude of electric force will be:
|F| = |q|*E
|F| = 1.6*10^-19*5*10^5
|F| = 8*10^-14 N
Direction of force on electron will be towards the opposite direction of electric field, meaning towards left
Let me know if you've any query.
