Three identical particles have the same mass m and positive charge Q. They are initial at rest in the corners of an equalateral triangle with sides a. One particle is released, What is the speed of the moving charge when it is a large (aka infinity) distance from the other two?

Oppositely charged parallel plates are separated by 5.64 mm. A potential difference of 600 v exists between the plates. (a) What is the magnitude of the electric field between the plates? N/C (b) What is the magnitude of the force on an electron between the plates? (c) How much work must be done on the electron to move it to the negative plate if it is initially positioned 2.92 mm from the positive plate?

Two large (treat as infinite) parallel conducting plates are charged to t Q as shown by the battery. A proton is released from rest at point A and is measured to be moving with a speed v, = 2 x 105 m/s when at point B. The right plate is then moved closer to the left as shown in the %3D X X rightmost figure. The experiment is repeated. What will be the speed of the proton at point B? A) Greater B) Smaller C) Equal D) Impossible to determine

The separation distance between the two plates of a parallel plate capacitor is 2.47 cm. An electron is at rest near the negative plate. When it is released, it accelerates and reaches the positive plate with a kinetic energy of 6.30 10-15 J.What is the magnitude of the electric field in the region between the plates of the capacitor?
