electric field due to 3 nC ( upper)
E = k q / r^2 = 9*10^9 * 3*10^-9 / 0.04^2 ( cos 30 i + sin 30 j)
E1 = 16875* (cos 30 i + sin 30 j)
similarly electric field due to 3 nC (lower)
E2 = 16875 * ( cos 30 i - sin 30 j)
electric field due to - 2 nC
E3 = 9*10^9* 2*10^-9 / 0.04^2 = - 11250 i
net electric field
E = E1 + E2 + E3
E = 16875 * 2* cos 30 - 11250
E = 17978.36 N/C
directed along +x axis
========
force acting on given charge
F = qE = 17978.36* 5*10^-9 = 8.99*10^-5 N
directed along - x axis
=======
plz post other problem seperately
do comment in case any doubt, will reply for sure.. Goodluck
