Two positive point charges 5.25 μC are fixed on the y-axis at y = 7.75 mm and y = -7.75 mm. A negative point charge -4.25 μC is located 10.0 mm on the x-axis. What is the x-component of the force on the -4.25 μC charge? What is the y-component of the force on the -4.25 μC charge? What is the magnitude of the net force on the -4.25 μC charge if it is located at the origin? Where must...

Two charges, one of 2.50?C and the other of -3.50?C, are placed on the x-axis, one at the origin and the other at x = 0.600...
Put two point charges on the same x (or y) axis, some distance apart, but fixed in place (immovable). One is positive, the other is negative, but their magnitudes are unequal. No other charges are nearby these two. There are two positions the same x (or y) axis where the net electric potential due to these two charges is zero. The question below can be answered for either position, but doesn't have to be answered for both. Question: choose one...
Three point charges are arranged along the x axis. Charge q 1 = -4.20 nC is located at x= 0.220 m and charge q 2 = 2.10 nC is at x= -0.330 m . A positive point charge q 3 is located at the origin. 1)What must the value of q3 be for the net force on this point charge to have magnitude 4.10 μN? 2)Where along the x axis can q3 be placed and the net force on it...
Five point charges are located on the y-axis. Two are positive with charge q = 0.54 mC and three are negative with charge q = -0.54 mC. The positive charges are a =4.5 m away from the origin, one on each side of it. Two of the negative charges are 2a away from the origin, one on each side of it. A negative charge sits at the origin. A positive point charge with charge Q= 6 mC is positioned on...
