Question

Point charges of -2.37 PC and +7.37 C are placed 0.745 m apart, with the negative charge at the origin and the positive charge on the +y-axis. (a) At what location, in meters, is the electric field due to these charges zero? Do not enter units with your answer. There is a support video for this class of problems. Add your answer

Answer 1

At y = -0.98 m  

Electric field will be zero.

• +7.3740 0.745m 2.37MC y + so at Y= -0.9758 let at point o electric field will be zero due to these charges E TER - 2.37 MCXK. 7.37XCXK 7² (140 745) KX2.37 MC 7.374 exk y2 +0.745 ) (y+0.745 ) ² = 31097² Y+0.745 = 1.76347 0.7634 Y = 0.745 Y = 0.9758 T 7= -0.98

Point P is below origin so answer is with negative sign.

Thanks for asking.
