An electron (m = 9.1 x 10-31 kg, q = -1.6 x 10-19 C) in the picture tube of a TV is accelerated from rest through a potential difference of AV = 5000 V. What is the final speed of the electron? CQ1: Which of the following is true? A) The electron accelerates from a region of lower potential to a region of higher potential (V, > V₁). B) The electron accelerates from a region of higher potential to a region of lower potential (Vƒ < V;). C) There's not enough information to determine whether A or B is true.

A line of charge with a non-uniform charge density λ=ay, where a=−10 nC/m2 lies along the y axis with one end at the origin and the other at y=h, where h=0.5 m. What is the total charge? What is the electric potential of this line charge at point P?

In the image provide these exists two parallel plates call A and B the length of both being 5 centimeters and both separated from each other with a distance of 4 centimeters. An electron enters 1 cm above plate B and it is traveling horizontally at speed of 1x10^6 m/s. VA = 20 V and VB = 10 V are the plate potentials, respectively. A) What is the electrical field (vector) between the plates? B) What is the electric potential V at the entry point of the electron and its initial potential energy? C) The electron eventually find the speed one of the plates, find out out witch one and the speed of the electron before the impact. D) What is the location along the place where the electron makes impact (take x =0 as the left edge of the plates). OFocus 81 F 0.

Problem 7:  Consider two points in an electric field. The potential at point 1, V1, is 26 V. The potential at point 2, V2, is 159 V. An electron at rest at point 1 is accelerated by the electric field to point 2. Part (a)  Write an equation for the change of electric potential energy ΔU of the electron in terms of the symbols given.   Part (b)  Find the numerical value of the change of the electric potential energy in electron volts (eV).  Part (c)  Express v2, the speed of the electron at point 2, in terms of ΔU, and the mass of the electron me.  Part (d)  Find the numerical value of v2 in m/s.
