Four point charges have equal magnitudes. Three are positive, and one is negative, as the drawing shows. They are fixed in place on the same straight line, and adjacent charges are equally separated by a distance d. Consider the net electrostatic force acting on each charge. Calculate the ratio of the largest to the smallest net force magnitude. Number i + A d Units + B + C d D

Three charges are located on an x-y axis.  q1 has a value of 2.0 mC and is at (0, 3m).  q2 has a value of 3.0 mC  and is located at the origin.  q3 has a value of 4.0 mC and is located at (4 m, 0).  Find the magnitude and direction of the force on q1.  Don't forget to convert mC to C.   Draw a clear diagram!

three-point charges have equal magnitudes, two being positive and one negative. these charges are fixed to the corners of an equilateral triangle as the drawing shows. the magnitude of each of the charges is 5.5 Uc and the length of the sides of the triangles are 2.5 cm. calculate the magnitude of the net force that each charge experiences. for this question you should have three answers in other words. What is FA, Fb, Fc?

The charges on three identical metal spheres are -11.4 μC, 3.80 μC, and 1.90 μC. The spheres are brought together so they simultaneously touch each other. They are then separated and placed on the x and y axes, as shown in the figure. Treat the spheres as if they were particles. What is the net force ((a) magnitude and (b) direction) exerted on the sphere at the origin? Express the direction as an angle in the range (-180°, 180°) with respect to the positive x-axis direction. 92 91 4.90mm 4.90 mm 93 -- SUPPO (a) Number i Units (b) Number i Units
