16. The net field components along the xand yaxes are 122net, net, 222000cossin,.444xyqqqEERRRθπε=−=−The magnitude is the square root of the sum of the components-squared. Setting the magnitude equal to E= 2.00×105 N/C, squaring and simplifying, we obtain 2111202cos(4)qqER+−=. With R = 0.500 m,q1= 2.00×10− 6 C and q2 = 6.00×10− 6 C, we can solve this expression for cos
