A metal sphere of radius 5.00 cm is initially uncharged. How many electrons would have to be placed on the sphere to produce an electric field of magnitude 1.43 x 105 N/C at a point 8.60 cm from the center of the sphere? electrons

Two infinite sheets plates with the same uniform charge density of 8.0 µC/m2 are vertically placed and parallel to each other. a distance d apart along the yz-plane. One plane passes through x = 3 cm while the other plate passes through x = -3 cm. The magnitude of the net electric field at the point (x =  5, y = 0, z = 0) is nearly   Question 3 options:   None of these   9.0 x 105 N/C   0   4.5 x 105 N/C

Problem 13:   An electron has an initial velocity of 5.15 × 106 m/s in a uniform 1.9 × 105 N/C electric field. The field accelerates the electron in the direction opposite to its initial velocity. Part A: How far does the electron travel before coming to rest in m?  Part B: How long does it take the electron to come to rest in s?  Part C: What is the magnitude of the electron's velocity (in m/s) when it returns to its starting point in the opposite direction of its initial velocity?

A small glass bead has been charged to + 30 nC . A tiny ball bearing 3.0 cm above the bead feels a 1.8×10−2 N downward electric force.

A small sphere is electrically neutral before 2.4 x 1011 electrons are added to it. At a distance of 13 cm from the center of the sphere what is the magnitude of the electric field and what is its direction (toward or away from the sphere)?

Two charges one negative and one positive with strength Q1 = -3*q and Q2= +2*q (where q=7.0 nC,q=7.0*10°C) are placed 3.6m apart. Pis located x distance from Q1, and is a point where the sum of the voltage of the two charges will sum to zero. What is the magnitude and direction in x-axis of the electric field at point P due to Q1 and Q2 in units of Newton/Coulomb? +2q 3.6

An alpha particle (a helium nucleus) is traveling along the positive x-axis at 1200 m/s when it enters a cylindrical tube of radius 0.400 cm centered on the x-axis. Inside the tube is a uniform electric field of 5.50  10-4 N/C pointing in the negative y-direction. How far does the particle travel before hitting the tube wall? Neglect any gravitational forces. Note: m? = 6.64  10-27 kg; q? = 2e. m
