b) Calculate the net force (magnitude and direction) exerted on charge q by the other four charges, in terms of q, Q, d, and e0. You may draw the force vector to indicate the direction. c) If the charge q is released from rest, and the four other charges held fixed, will the charge q ever “escape” to infinitely far away (assuming an infinite amount of time can pass)? Justify your answer.

A positively charged particle Q1=+25 nC is held fixed at the origin. A second charged Q2 of mass m=8.5 ug is floating a distance d=25 cm above charge Q1. The net force on Q2 is equal to zero. You may assume this system is close to the surface of the Earth.  b. Calculate the magnitude of q2 in units of nanocoulumbs.

A thin, insulating rod of length Icarries a linear charge density^(x) that varies with distance according to (x)=Ax (in SI units). The location of the origin is shown in the figure. A point charge q is located a distance I from the end of the rod as shown. a. What are the SI units of the constant A? b. Find the force that the rod exerts on q.

Two 2.0-g aluminum foil balls hang from 1.0-m-long threads that are suspended from the same point at the top. The charge on each ball is +4.0×10^−9C. a) Determine the angle between the threads. Assume the gravitational force is much greater than the electrostatic force. b) Determine the tension force exerted by the string.
