Your task is to build a 2‐player "rock paper scissors" game. each player can enter their selection by pressing a pushbutton switch. your design must switch on an led that corresponds to each player to show which player won– i. e., led1 is associated with player 1 and led2 associated with player 2 (use different color leds if available). if player 1 wins then led1 lights up, if player 2 wins then led2 lights up, and all other cases neither led lights up.

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.
