An electron is sitting at rest. Suddenly, it experiences an upward acceleration

Question

An electron is sitting at rest. Suddenly, it experiences an upward acceleration of 10^18 m/s^2 for a very short time (a bump). Location A is 15 meters from the electron, in a direction perpendicular to the acceleration. a) One nanosecond after the bump, what are the magnitude and direction of the electric field at location A due to the electron? b) How long after the bump does the electric field at location A change? c) What is the direction of the radiative electric field at location A when it reaches A? d) What is the magnitude of this radiative electric field? How does it compare to the magnitude of the electric field at A one nanosecond after the bump? . e) Just after the field changes, what is the direction of the magnetic force on a proton that was initially at rest at location A? (Explain with a diagram.)
