    Consider a charge of +6×10^−7 C located at position (x=4,y=2,z=2)(x=4,y=2,z=2) m. We are asked to find the electric field at point P which is at (x=8,y=−2,z=4)(x=8,y=−2,z=4) m. What is the y-component of the electric field at point PP? Remember to give your answer in terms of N/C, and use k=9×10^9.

    If we assume that x is very small compared to 0.00250, the first iteration gives x=(0.00250×4.5×10−4)1/2=0.00106. Even though the assumption is not valid, it seems likely that [HNO2] is closer to (0.00250−0.00106)M than to 0.00250 M. Substitute the new value into the original equation to obtain the second iteration, x20.00250−0.00106=4.5×10−4 and then x=8.04×10−4. Now, we can restrict x to the following range: 8.04×10−4<x<1.06×10−3 Use the new value of x to write that [HNO2]=(0.00250−0.000804)M and solve the equation once again for...
