An electron is projected from a distance d and with initial velocity parallel to a uniformly charged flat conducting plate carrying surface charge density as shown. Neglecting gravity, the distance where it falls off on ground is:

An electron falls a distance of 4 cm in a uniform electric field of magnitude The time taken by electron in falling will be-

The figure below shows an electron entering a uniform electric field perpendicularly betweenthe middle of two plates with a velocity of 5.0 × 107 m s−1. Two flat parallel plates, each oflength 12.0 cm, are separated by a distance of 1.5 cm.The potential difference between the plates is 210 V.(a) Calculate the magnitude of the electric field strength between the plates.(b) Determine the magnitude and direction of the acceleration of the electron.(c) Calculate the time for the electron to travel a horizontal distance equal to the length of theplates.(d) Use your answers in (c) to determine whether the electron will hit one of the plates oremerge from between the plates.

The charge to the left in the figure above has a magnitude of 5.50 nC, and charge to the right has a magnitude of 1.375 nC. The distance between them d is 6.50 m. Where can you place an electron along x other than at infinity such that it is in static equilibrium? Take the origin of coordinates at the left charge.x =:

An electron is placed in an electric field of intensity 104 Newton per Coulomb. The electric force working on the electron is:a.0.625×1013Nb.0.625×10-15Nc.1.6x1015Nd.1.6x10-15N

In the figure above, an electron is released at an angle of 45 degrees from the parallel-plate capacitor's positive side. The distance between the plates is 2.50 cm and the electric field strength inside the capacitor is 3.50×104 N/C. If the electron avoids touching the negative plate, what is its maximum possible initial speed?
