(CLO-1} A positive point charge q= 18.8 nC is located at (-a, -a) with a 11.2 cm (see figure below) What must be the algebraic value, in unit nC (nano Coulomb), of another point charge g, located on x-axis at (b. 0) with b 17.5 cm in such a way the net electric field created by the two charges at the origin has only one component along y-axis (Ey 0 at O)? Enter your answer as algebraic (positive or negative) decimal number with 1 digit after the decimal point. Don't enter the unit "nC. Remark: error of sign is completely wrong answer. y4 Selected Answer: O 16.2
