An electron is released from rest at the negative plate of a parallel plate capacitor. The charge per unit area on each plate is = 2.0 × 10-7 C/m2, and the plates are separated by a distance of 1.9 × 10-2 m. How fast is the electron moving just before it reaches the positive plate? ty for any help :)
The two charges on the X axis are equidistant from the origin and also are identical. Hence their electric field at origin will be equal in magnitude and opposite in direction and will cancel out. Hence the electric field at origin is only due to Q3 and Q4.

Two charges are located on the x axis: q1 = +5.5C at x1 = +5.4 cm, and q2 = +5.5C at x2 = -5.4 cm. Two other charges are located on the y axis: q3 = +3.5C at y3 = +4.8 cm, and q4 = -10C at y4 = +6.4 cm. Find (a) the magnitude and (b) the direction of the net electric field at the origin. please help!!! Two charges are located on the x axis: q1 +5.5 1C...
An electron is released from rest at the negative plate of a parallel plate capacitor and accelerates to the positive plate (see the drawing). The plates are separated by a distance of 2.4 cm, and the electric field within the capacitor has a magnitude of 1.8 x 10% v/m.

Two charges are located on the x axis: q1 = +4.5C at x1 = +5.4 cm, and q2 = +4.5C at x2 = -5.4 cm. Two other charges are located on the y axis: q3 = +2.9C at y3 = +4.8 cm, and q4 = -11C at y4 = +7.6 cm. Find (a) the magnitude and (b) the direction of the net electric field at the origin.
Velocity of Electron in Capacitor An electron is released from rest at negative plate of the parallel plate capacitor and accelerates to the positive plate as shown in Fig.7. The plate are separated by a distance Ax = 2.0 cm, and the electric field within the capacitor has a magnitude of 3xl06 V/m. Determine the velocity of the electron just as it reaches the positive plate. ( Me-= 9.1lxlO-3lkg)
