1. hree charges and an infinitely lng charged line are placed as shown below, where -q -1.6x10 C,- 4.0x10 C/m, and 8-30 93 42 a. Ifd 2cm is the distance from qu to the origin, what distance D must the line charge λ be placed from the origin in order to ensure that there is no net electric force on gi? b. Ifcharges 2 and 3 were moved further from the x-axis, would the necessary value of D increase, decrease,...

Two charges one is +23 nC and +2* 23nC are separated by 1m distance. What is the electric field at mid point of the line joining the charges?
2. Three charges are fixed at positions along the a-axis as positions -d, o, and +d. The charges at -d and d are both and the charge at O is positive. (a) A positively charged object of mass m is placed on the x-axis between O and d, close to the positlicn the three charges described above do not move as a result of this new charged object, describe the mois object after it is released as it moves in...
two point charges of magnitude positive 3 UC and -5 UC are placed along the x-axis at x equals 0 centimeters and y equals 40 cm respectively.where must a third charge q be placed along the x axis so that it does not experience any net force because of the other two charges.
Problem 2 -Superposition Principle for electrie forces between point charges Two charges are positioned along the horizontal -axis. 6.0 uC is positioned in the origi 02 =-60 pC is positioned at x = 2.0 m. A third charge 03-3.0 pC is placed halfway betwe 01 and 02 (at the point x = 1.0 m).
