Assuming I did it correctly:
F=ma
mass = the mass of the electron = 9.11 * 10^-31 kg
a= 115 m/s
plug in your known variables
F will equal 1.05 * 10^-28 Newtons (N)
Next, F=qE
q equals the charge of the electron, or "point charge".
q=1.6 * 10^-19 C
Solve for E, so E=F/q
plug in your values, and E will equal 6.56 *10^-10 N/C
