Explanation / Answer

q = 18 nC
We know,
Electric Field due to point charge is given by, E = k*q/r^2
Where r is the radial distance

For Part A, r = 5.0 cm = 5.0 * 10^-2 m
For Part B & C , r = 5*sqrt(2) = 7.07 cm = 7.07 * 10^-2 m

Part A,
E = (8.9 * 10^9 * 18 * 10^-9)/(5.0 * 10^-2)^2
E = 64080 N/C
E = 6.4 * 10^4 N/C

Part B & C
E = (8.9 * 10^9 * 18 * 10^-9)/(7.07 * 10^-2)^2
E = 32050 N/C
E = 3.2 * 10^4 N/C
