Use Coulomb’s law to determine 0d,-jdbj l.nbthz; hp h etjm+*byzt3,7e magnitude and direction of the electric field at points A and B in Fig. 16–57 due to the two positivpty7 e,z tb+*3 zhj;hme charges $(Q\,=\,7.0\mu C\,)$ shown. Are your results consistent with Fig. 16–31b?
$E_A$ =    $ \times10^{6 }\,N/C$
$\theta_A$ =    $^{\circ}\,$
$E_B$ =    $ \times10^{7 }\,N/C$
$\theta_B$ =    $^{\circ}\,$
