Explanation / Answer

given,

charges of magnitude = 3 * 10^-9 C and -3 * 10^-9 C

r = 6.5 cm

distance between the point and charge is d

d = sqrt(r^2 + r^2)

d = sqrt(0.065^2 + 0.065^2)

d = 0.0919 cm

electric field = kQ / d^2

electric field due to positive charge = 9 * 10^9 * 3 * 10^-9 / 0.0919^2

electric field due to positive charge = 3196.927 N/C

electric field due to negative charge will be = -3196.927 N/C because magnitude abd distance is same

angle between two electric fields is 90 degree

so

net electric field = sqrt(2) * 3196.927

net electric field = 4521.1375 N/C

by symmetry we can say that direction will be toward -ve y axis
