Asmall charged sphere is attached to a thread and placed in an electric field. the other end of the thread is anchored so that when placed in the field the sphere is in a static situation (all the forces on the sphere cancel). the sphere has a mass of 0.018 kg and contains a charge of – 64.30 x 10^3 c. the tension in the thread is 6.57 x 10^-2 n. show your work and/or explain your reasoning. if the thread is horizontal, find the magnitude and direction of the electric field. 2. now the same particle is removed from the thread and placed below the center of a charged plate and released. are there any conditions under which it is possible for the particle to be suspended in the air below the plate? show any relevant calculations and explain your reasoning

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
