Explanation / Answer

from fig angle at the lowr charge side = teta = tan^-1(4/3)= 53

a) F on lower due to charge on x F1 = k*q^2/r^2=0.02916 N toward -q

F on lower due to charge on y F2 = k*q^2/r^2=0.02916 N angle between them is 74

Fnet =sqrt(F1^2 +F2^2+2*F1*F2cos74)= 0.047 N

b) F on right due to charge on x F1 = k*q^2/ 8^2= 0.0113N

F on right due to charge on lower F2 = k*q^2/r^2= 0.02916N

angle bet ween tmem is 37

F net = sqrt(F1^2 +F2^2+2*F1*F2cos37)=0.039 N
