Coulomb's Law PhET Simulation Activity - Assignment 4

PhET Simulation: Coulomb's Law Before we explore electric currents, let’s review Electrostatic Force / Static Electricity using the PhET Simulation: Coulomb’s Law!Click the link above then select Macro Scale. Investigate! Complete the table below. Include all decimal points Charge 1 (µC) Location 1 (cm) Charge 2 (µC) Location 2 (cm) Force of 1 on 2 (Newtons) Force of 2 on 1 (Newtons) 10 3 10 7 561.722 561.722 10 1 10 9 140.430 140.430 10 1 5 9 70.215 70.215 5 1 -5 9 35.108 35.108 As distance between the two objects increases, the electric force _. increase decrease stay the same As charge increases, the electric force _. increase decrease stays the same If objects have different charges, the more charged object applies a(n) _ force compared to the less charged object. greater lesser equal The electric force is a force of attraction or repulsion between objects based on their charges and their distance apart. Match the following statements. Electric force is attractive Opposite charges Electric force is repulsive Like charges Review Practice In equation form, Coulomb's Law can be stated as:Q1 and Q2 represents the quantities of charge on objects 1 and 2 (in Coulombs), respectively, while d represents the distance of separation between the centers of two charged objects (in meters). The symbol k is known as the Coulomb's Law constant. The value of this proportionality constant is dependent upon the medium in which the charged objects are located. In the case of air, the value is 8.99 x 109 N • m2 / C2. The SI unit for electrostatic force, as in any type of force, is in Newtons (N).Click on the blue Coulomb's Law to read more about the equation and see several examples worked out for you. There is section of text relating electric and gravitational forces. Suppose that two point charges, each with a charge of +1 Coulomb are separated by a distance of 1 meter. Determine the magnitude and direction of the electrical force between them. 9 x 109 N towards each other 9 x 109 N away from one another Two balloons are charged with an identical quantity and type of charge: -0.0025 C. They are held apart at a separation distance of 8 m. Determine the magnitude of the electrical force of repulsion between them. 878 N 7,023 N 9.77 x 10-8 N Two charged boxes are 4 meters apart from each other. The blue box has a charge of +0.000337 C and is attracting the red box with a force of 626 Newtons. Determine charge of the red box. Remember to indicate if it is positive or negative. 1.18 x 108 C -1.18 x 108 C 0.0033 C -0.0033 C A piece of Styrofoam has a charge of -0.004 C and is placed 3.0 m from a piece of salt with a charge of -0.003 C. How much electrostatic force is produced? - 12,000 N 12,000 N 1.33 x 10-6 N -1.33 x 10-6 N The electron and proton of a hydrogen atom are separated, on average, by a distance of about 5.3 x 10-11 meters.Mass of electron = 9.109 x 10-31Mass of proton = 1.673 x 10 -27Charge of electron = -1.60 x 10-19 CCharge of proton = +1.60 x 10-19 CCalculate both the gravitational and electric force. Which force is stronger, the gravitational force or the electric force? electrical force gravitational force
