Magnetic Field Lab
Sandeep Dulai
Purpose: To measure and determine the relationship between a magnetic field generated by a
line of current.
Hypothesis: I believe the magnetic field will be between 1.00*10^1 AND 1.00*10^2 because
the greater the current
Balloon Experiment Using Coulombs Law
Title:
How Many Electrons?
Theory:

See Attached
Objective:
 To determine the charge and number of excess electrons on a balloon by applying Coulombs
law and Newtons 3rd Law of motion.
Materials:

Balloons.
Thread.
ELECTROSTATIC CHARGE ON A BALLON
Purpose
The objective of this lab is to calculate the charge of the balloon when rubbed with a fur
cloth. By doing so, we will determine whether it follows Coulombs law or not.
Hypothesis
I think that the lab will follow C
JJ THOMSONS: CATHODES RAY EXPERIMENT
Purpose
The objective of this lab is to calculate the
Q: M ratio of an electron in a cathode ray
using J.J. Thomsons Cathode ray experiment.
Hypothesis
The value of the
Q: M
ratio that I will obtain in my lab should be
Converging Lens Lab
Purpose: The purpose of this lab is to find the focal length of an converging lens and to find the
relationship between 1/di versus 1/do graph.
Hypothesis: We believe that the graph of 1/di versus 1/do will be a linear line with a nega
