A charge -3.0nC is placed at the origin of an x-y coordinate system, and a charge 2.0nC is placed on the positive y-axis at y = 4.0cm. a) if a third charge 5.0nC is now placed at the point x= 3.0cm; y = 4.00cm, find the x- and y-components of the total force exerted on this charge by the other two. b) Find the magnitude and direction of this force.

Three charges are placed on a horizontal line. Charges q1 = +7 nC and q2 = -3 nC are fixed in place, with q2 2.0 m to the right of q1. Charge q3=+5 nC is in equilibrium but free to slide on the line (but not off of it.) a. Find the distance between q3 and q1 and whether q3 is to the right or left of q1. b. If q3 can move along the line away from its initial location, is the equilibrium stable or unstable? How did you decide? c. If q3 were were on a vertical line instead, so it could move up and down but not horizontally, would the equilibrium be stable or unstable for that motion? How did you decide? m
3. A 7.17 nC charge is located 1.66 m from a 4.42 nC point charge. a. What is the magnitude of the electrostatic force that the 7.17 nC charge exerts on the 4.42 nC charge? b. What is the magnitude of the electrostatic force that the 4.42 nC charge exerts on the 7.17 nC charge? C. Are these forces attractive or repulsive?
A sphere with a radius of 1.5cm hangs by an insulating thread. The sphere is attracted to a positively charged rod held near the sphere. a) If the ball is made of an insulating material, what can you say about the charge on the sphere? Be specific and explain your answer. b) If the ball is made of an conducting material, what can you say about the charge on the sphere? Be specific and explain your answer.
1. Three charges form an equilateral triangle of side length d. The top charge is 93Q and is located on the y-axis, while the bottom two are q₁ = 92 = 4Q and are located on the x-axis. What is the net force acting on q3? -4kQ2 d² (2) -4kQ2 j -AkQ² (3) (4) -8kQ² +√√3kQ² (5) d2 d² 3d² d²
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.
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.
