(3%) Problem 9: Two charges are to be placed on the x axis. The first, a -2.5 µC charge, is placed at x = 45 cm. ▷ 50% Part (a) If the second charge is +4.5 µC, where should it be placed, in centimeters, to achieve a net zero electric field at the origin? x = cm Grade Summar Deductions Potential Late Work % Late Potential sin() cos tan() 7 HOME T ( EM^^ 8 9 4 5 6 cotan() asin() acos atan() acotan() 1 2 3 sinh() cosh() tanh() cotanh() Degrees O Radians Submissions Attempts remain (0% per attemp detailed view + 0 .

Then relate the magnitudes of the different contributions.
