I had a few questions which I'd appreciate some help with:(adsbygoogle = window.adsbygoogle || []).push({});

Q3) A charge of 6 mC is placed at each corner of a square .100 m on a side. Determine the magnitude and direction of the force on each charge.

I essentially found the force on one corner ( by using x and y components )

Hence, for X = 2.29E7 + 0 + 3.24E7

For Y = -2.29E7 +3.24E7

I found the force to be 5.6E7. is this correct?

Q4) A +4.75 micro C and a -3.55 micro C charge are placed 18.5 cm apart. Where can a third charge be placed so that it experiences no net force?

not sure how to go about this. Do I say:

Q1+Q2+Q3=0

Hence, F/E+F/E+F/E=0 ????
