Answer:(a)

(b)

Explanation:Parameter given:

Electric field, E =

(a) Electric force is given (in terms of electric field) as a

product of electric charge and electric field.Mathematically:

Electric charge, q, of an electron =(b) This electrostatic force causes the electron to accelerate with an equivalent force:

F = -ma

where m = mass of an electron

a = acceleration of electron

(

Note: the force is negative cos the direction of the force is opposite the direction of the electron)Therefore:

Mass, m, of an electron =

=>

The acceleration of the electron is
