Answer

A proton is initially at rest. At time t = 0, it is accelerated upward with an ac- celeration of 25000 m/s for a short time, At = 5x107Y s . We make observations at location A, 17 m from the proton as in the figure below. a = 25000 m/s* Take the +x direction to be toward the right, the +y direction to be upward, and the +2z direction to be out of the page (toward you). What is the direction of the electric field at location A at time t = 5.5x 107 s? AND What is the direction of the radia- tive electric field at location A at time t = 5.83333 x 10~ s? Choose the unit vec- tors corresponding to these directions. Re- member that Z is in the positive z-direction and that is in the positive y-direction
