A positive charge Q1 = 49.5 nC is located at the origin. A negative charge Q2 = -9.5 nC is located on the positive x-axis p = 7 cm from the origin. Calculate the location, x, on the x-axis, in centimeters, where the electric field is equal to zero.

Acertain half-reaction has a standard reduction potential e_red^0 = -0.94 v. an engineer proposes using this half-reaction at the cathode of a galvanic cell that e must provide at least 1.00 v of electrical power. the cell will operate under standard conditions. a. is there a minimum standard reduction potential that the half-reaction used at the anode of this cell can have? b. is there a maximum standard reduction potential that the half-reaction used at the anode of this cell can have?
