Objectives Obtain the value ofthe electric constant, k. Theoretical Background Coulomb's Law: "The magnitude of the electric force that a particle exerts on another is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.\" Mathematically, the magnitude of this electrostatic force F; acting on two charged particles ((11, :12) is expressed as: Where r is the separation distance between the charged objects and k is a constant of proportionality, called the Coulomb constant, k = 9,0 x 109 Nm3/C2. Procedure 1. Click on the following link and x the charge q1=2uC and q2=4uC write their values in the table 1 Calculate the percentage error in k (kmwn:9.0 x 109 le 2. Change the distance between the two charges as shown in the Table 1. 3. Record the force value for each dis- tance in Table 1
