What is the vector force exerted on a 4.45 uC charge by an electric field E = (245? 1253) WC? Express your answer in vector form. F: N Additional Materials [3 Reading Submit Answer -I1 Points] OSUNIPHYS1 22.4.WA.034. ASK YOUR TEACHER PRACTICE ANOTHER You charge a piece of aluminum foil (mass = 564 g) by touching it to a charged rod. The charged rod gives the aluminum foil a charge of ~12 uC. Your professor brings a charged plate over and tells you to put the aluminum foil on top of the plate. To your surprise, the aluminum foil hovers motionless in the air above it! Calculate the value of the electric field from the charged plate (assume it is a uniform field and the aluminum foil is a point charge). magnitude _ .i'i/C direction Additional Materials L3 Reading
