What path does the electron follow in the electric field when the electron is projected normally in the field?

An electron passes through a space without deviation. Does it mean, there is no electric or magnetic field?

Is there any condition that an electron does not experience any force inside a magnetic field?

Are the specific charges of an electron and proton the same? Explain.

Oil has a density of 800 kgm^-3. A 1 $\rm\mu m$ diameter oil droplet acquires 10 extra electrons as sprayed. What potential difference between two parallel plates 1 cm apart will cause the droplet to be suspended in the air?
