16. The net field components along the x and y axes are 12 2 net, net, 22 2 00 0 cos sin ,. 44 4 xy qq q EE R RR θ πε =− = The magnitude is the square root of the sum of the components-squared. Setting the magnitude equal to E = 2.00 × 10 5 N/C, squaring and simplifying, we obtain 2 11 1 2 0 2c o s (4 ) q q E R +− = . With R = 0.500 m, q 1 = 2.00 × 10 6 C and q 2 = 6.00 × 10 6 C, we can solve this expression for cos
