1. 1 . [1 point, 10 tries] A 4.32×10 -9 C charge is located 3.36 m from a -3.02×10 -9 C charge. Find the magnitude of the electrostatic force exerted by one charge on the other. Answer: 1.04e-08 N 2. 2 . [1 point, 10 tries] Calculate the Coulomb force on q 1 , as seen in the figure below. Choose forces to the right be positive and forces to the left negative. Assume q 1 = 1.96 µC, q 2 = 5.76 µC and q 3 = -2.52 µC. r 1 = 3.43 cm and r 2 = 1.89 cm. Answer: -7.06e+01 N 3. 3 . [1 point, 10 tries] Calculate the Coulomb force on q 2 . Answer: 4.51e+02 N 4. 4 . [1 point, 10 tries] Calculate the Coulomb force on q 3 . Answer: -3.81e+02 N 5. 5 . [1 point, 10 tries] Three point charges are arranged as shown. Find the vector electric field that the q 2 and q 3 charges together create at the origin. Take q 1 =4.98×10 -9 C, q 2 =-3.00×10 -9 C, q 3 =6.16×10 - 9 C, a=0.321 m and b=0.104 m.
