Mathematically, the magnitude of this electrostatic force F eacting on two charged particles (q1, q2) is expressed as: Fe= kq1q2 r2 Wherer is the separation distance between the charged objects and k is a constant ofproportionality, called the electric constant (or Coulomb's Constant), k = 8.9876 10 9Nm2/C2. K c is called Coulomb's Force Constant or Electrostatic Force Constant. According to Ohm's Law, if you have a simple circuit (Figure 3), what happens to the voltage and current of the resistor as the resistance increases? Density is recorded in units of grams per cubic centimeter (g/cm 3).

Outline the procedure you will use you could use the method and diagram for the prelecture video of Chapter 20, just as is found in the study area of this chapter) to carry out the experiment including data collection and analysis. 1 Lab - Coulomb's Law - Phet Simulation This activity consists of two Parts Part one: Eclectic force versus distance. b) Since both balloons were charged with the same number of rubs, you can assume that q 1 and q 2 are equal. SET thevaluesofq 1 to-7 Candq 2 to10 C. 3. Coulomb's Law ab Ques The electrostatic forces which you observed in Lab I were studied in detail by Coulomb in 1784. The Coulomb's law describes the interaction between point charges. d) Write an equation that describes the primary force at work on the hanging balloons in Table B, Figure 1 under An experiment is carried out to test this relationship between F and r. Report this experiment using the format given on the previous page. Suppose that you do this experiment in the lab with q1 = 5 C and q2 = 3 C you find the following data (where cN is centi-newtons i.e. Note qualitatively how the forces are affected by these changes. It is because of humidity. The value of the charge on an electron is 1 x 10 You'll get a detailed solution from a subject matter expert that helps you learn core concepts. You can also move the ruler. Lab experiment #5 [Based on PASCO Coulomb's Law lab, rewritten by Geoffrey R. Clarion] Experiment Introduction The Coulomb Balance (Figure 2) is a delicate torsion balance that can be used to investigate the force between charged objects.

Include error bars (of 5%) on each data point plotted on the graph. Lab 2 Coulomb's Law Using Phet Interactive Simulation This activity consists of two Parts Part one: Eclectic force versus distance. Part one: Eclectic force versus distance. a distance r away from each others, the Coulomb Law gives the force as F = k q1q2 r2 where k = 8.99 109 Nm2/C2 is the Coulomb constant. We will attempt to verify that the value of the exponent of R is 2 and that the force is proportional to the product of the two charges . resultant vector that shows the tension on the string, labeling it with the equation FT = Fg + Fe. With the aid of virtual equipment, it was possible to charge the ball on the pole by rubbing the. For this reason, you will be using a computer simulation instead. Obtain a value for the Coulomb law constant. a) Using the triple beam balance, find the mass of a balloon. Step 19: Answer the follow-up questions. Lastly, the strength of an, electric field E at any point is the force F per units of positive electric charge q which is the, E1 = q1*k*(x+a)./abs(x+a).^3;%electrical field one, x=/=1 and x=/=-1, E2 = q2*k*(x-a)./abs(x-a).^3;%electrical field two, q2 = -1*10^-9; %made this a negative charge, replot, x = -2.1:0.2:2.1; %484points are calculated, y = -2.1:0.2:2.1; %484 points are calculated, title 'Electric Field (Velocity plot of vectors)', title 'Electric field with positive q2 value', q2 = -1*10^-9;% change charge to a negative, replot. Although it is possible, using this apparatus, to measure the value of the constant, k, appearing in Coulomb's Law, we will not attempt to do so in the present experiment. Chegg.comPhysics 136-2: General Physics Lab Laboratory Manual . Lab procedure: All graphs should have a corresponding data table, and, if possible, done using EXCEL. 1. No, the thickness does not affect the results, only if the weight and area increase or decreases. b) Record only the resulting angle in Table E and the number of electrons transferred in Table F. Instruments used: voltmeter, laser, two metallic plates, ruler, meter stick, a power supply. /Filter /FlateDecode 5. Both are available online if you google "experimental determination of Coulomb's law. 1 below demonstrates the setup and the free-body diagram for the force analysis.
