At time $t=0,$ a point charge with $-3\mathrm{.}2C$ accelerates very briefly in the direction having an angle $0\mathrm{.}2$ rad with the $+x-$axis. The magnitude of its acceleration is $4{10}^9\frac{m}{s^2}.$ An electric$/$magnetic field detector is placed at location $A,5$ meters from the electron, as shown in the diagram.

A$.$ At what time $t_1$ does the detector at A first detect radiative electric and magnetic fields?

$s$

B$.$ Calculate the radiative component of the $\backslash$textbf$\{$electric$\}$ field detected at location $A$ at time $t_1$ due to the accelerated electron.

$E_x=\frac{V}{m}$

$E_y=\frac{V}{m}$

$E_z=\frac{V}{m}$

C$.$ Calculate the radiative component of the $\backslash$textbf$\{$magnetic$\}$ field detected at location $A$ at time $t_1$ due to the accelerated electron.
