Why can you make a goal without hitting the puck in electric field hockey? Why can you use either a positive charge or a negative charge to move the positively charged puck? What do you think would happen if you use 2 charges instead of one to make the puck move?

One particle has a mass of 3.71 x 103 kg and a charge of +7.56 μC. A second particle has a mass of 7.17 x 103 kg and the same charge. The two particles are initially held in place and then released. The particles fly apart, and when the separation between them is 0.177 m, the speed of the 3.71 x 103 kg-particle is 126 m/s. Find the initial separation between the particles.

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.

Three point charges are located in free space along the x-axis. A positive charge of +2 uC is located at x = 0, a negative charge of -3 μC is located at x = 3 m, and a positive charge of +4 μC is located at x = 6 m. a. Will q1 and q2 attract or repel? Blank 1 b. Will q1 and q3 attract or repel? Blank 2 c. What is the direction of the electrostatic force acting on q1 due to q2? (north, south, east, or west) Blank 3 d. What is the direction of the electrostatic force acting on q1 due to q3? (north, south, east or west) Blank 4 For the following questions, convert your answer into PROPER SCIENTIFIC NOTATION and round the coefficient to two decimal places.(e.g. 5.43 x 10²: 5.43 is the coefficient) What is the magnitude of the electrostatic force on q1 due to q2? Blank 5 x10^Blank 6 N What is the magnitude of the electrostatic force on q1 due to q3? Blank 7x10^Blank 8 N Calculate the net electric force on the positive charge at x = 0 due to the other two charges: Blank 9 x 10^Blank 10 N
