An electron is initially at rest. At a time t1 = 0 it is accerated upward with an acceleration of 10^18 m/s^2 for a very short time (this large acceleration is possible because the electron has a very small mass). We make observations at a point A, which is 15 meters to the right of the electron's initial position.(adsbygoogle = window.adsbygoogle || []).push({});

a. At time t2 = 1 ns, what is the magnitude and direction of the electric field at point A?

b. At what time t3 will the electric field at location A change?

c. What is the direction of the radiative electric field at location A at time t3?

d. What is the magnitude of this radiative electric field?

e. Just after time t3, what is the direction of the magnetic force on a positive charge that was initially at rest at location A? Explain with a diagram.

I need equations for (a) and (b) at least. Thanks.
