There are two types of observations: qualitative and quantitative.
qualitative observations use words to describe what is observed during the experiment. these
notes are kept in a journal or logbook. quantitative observations use numbers, such as calculations
and measurements that are recorded in data tables. scientists around the world use the same
system of measurement called the metric system. in your experiment, the unit for volume is cubic
meters (m
3
). the unit for temperature is kelvin (k). create a data table for the quantitative data of
the lab.

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.
