Activity 1: Coulomb's Law 1. Start the Coulomb's Law PhET simulation and explore it. Choose the Macroscale tab. Make sure that the Force Values and the Scientific Notation boxes are checked. Fore on by 9,719.004 N Force ong, tyg, 719.004 N SEE the forces in the system MEASURE the distance between charges Charge 1 Charge 2 VIEW forces in standard or Colomb's Lim PHET scientific notation 2. For the pair of charges q₁ and 92, positioned at x₁ and x₂ respectively, listed in Table 1 below, investigate if the electric force is attractive or repulsive. The distance between charges is denoted by the symbol r. +Table 1: 91 92 X1 X2 r F12 F21 Force (attractive (μC) (μC) (cm) (cm) (cm) (N) (N) or repulsive) -4.0 -4.0 -4.0 -4.0 -4.0 +4.0 +4.0 -4.0 +4.0 +6.0 +2.0 +2.0 +2.0 +2.0 +2.0 +2.0 -3.0 +2.0 -3.0 +2.0 -3.0 +2.0 -3.0 +2.0 -3.0 +2.0 -3.0 +3.0 -3.0 -2.0 -3.0 -1.0 -3.0 -3.0 +2.0 +2.0 -1.0 +3.0 -1.0 +4.0 -1.0 +5.0 -1.0 +6.0 -1.0 1.0 2.0 3.0 4.0 5.0 1.0 1.0 2.0 2.0 2.0 2.0 2.0 2.0 2.0 2.0 2 For W Sco
