There are 3 thin conductive infinitly thin spherical shells with a charge on each shell of +2Q. The innermost shell has a radius of R. Another of the shells has a radius of 2R. The outermost shell has a radius of 3R.  Draw a graph of E vs R. Make sure to show the values of E(3R), E(2R), and E(R).  Note: (put R on the x axis)

Your answer is partially correct. The charges and coordinates of two charged particles held fixed in an xy plane are q1 = 2.13 µC, x1 = 4.35 cm, Y1 = 0.304 cm and 92 = -5.93 µC, x2 = -2.30 cm, y2 = 1.07 cm. Find the (a) magnitude and (b) direction (with respect to +x-axis in the range (-180°;180°]) of the electrostatic force on particle 2 due to particle 1. At what (c) x and (d) y coordinates should a third particle of charge q3 = 6.16 µC be placed such that the net electrostatic force on particle 2 due to particles 1 and 3 is zero? (a) Number 25.3 Units N (b) Number i 173.44 Units ° (degrees) (c) Number -3.6 Units m Number i 0.42 Units m

There are two uncharged concentric conducting spherical shells and a separate point charge. The smaller shell has an inner radius of 0.100m and an outer radius of 0.200m. The larger shell has an inner radius of 0.300m and and outer radius of 0.400m. A point charge of +10.0μC is placed between the two shells at a radius of 0.250m from the origin. Determine the net charge on each of the four surfaces (r = 0.1,0.2, 0.3, 0.4) and make a sketch that indicates BOTH the electric field lines and the surface charge densities. (this sketch does not have to be exactly mathematically correct, but use intuition)

A +2nC point charge is located in between a +5nC charged flat plate of area 1.2m2 and another point charge of -3nC. The latter is located 6mm to the right of the first (+2nC) point charge, along a line that intersects the plate at 90o. The plate is located 4.3mm from the first, (+2nC) charge. A) What is the total electric force exerted on the +2nC charge? B) What is the total electric force exerted on the -3nC charge? C) What is the total electric field “seen” by the +2nC charge, as generated by the -3nC and +5nC objects? D) What is the total electric field (magnitude and direction) “seen” by the +2nC charge, as generated by the -3nC and +5nC objects?  E) What is the electric field generated by flat plate (magnitude and direction), a distance 0.5mm away from it? F) What is the total electric field (magnitude and direction) generated by all three charges, at a location 2mm to the right of the -3nC charge?

A charge +q is located at the origin, while an identical charge is located on the x axis at x = +0.74 m. A third charge of +2q is located on the x axis at such a place that the net electrostatic force on the charge at the origin doubles, its direction remaining unchanged. Where should the third charge be located?
