    Electric Field by two charge adjacent to fourth side= 2 ×9×10^9× 4/(2/100)^2 = 18×10^13N/C. Distance from farthest charge = 8^1/2= 2×2^1/2 . Electric field by this charge on fourth one= 9×10^9×4/((2×2^1/2)/100)^2 = 4.5×10^13 N/C. Total Electric Field = 10^13(18+4.5) = 22.5×10^13 N/C

    1Thank You

    A Last 5 years ago

    force by two charge adjacent to fourth side= 2 ×9×10^9× 4×4/(2/100)^2 = 7.2×10^14 Newton distance from farthest charge = 8^1/2= 2×2^1/2 force by this charge on fourth one= 9×10^9×4×4/((2×2^1/2)/100)^2 = 1.8×10^14 Newton Total Force = 10^14(7.2+1.8) = 9×10^14 Newton
