Part (a) Enter an expression for the electric flux De at the surface of the van in terms of the total charge on the van. Use Gauss's law and the definition of electric flux to enter an expression for the average magnitude of the electric field Ey at the surface of the van. Assume the electric field is constant over the surface of the van and let A represent the total surface area of the van. Your expression should be in terms of the total charge on the van and the surface area. Part (c) Assume the loose power line came to rest on a small hatchback car which has each of its three dimensions equal to exactly one half of the dimensions of the van. The power line deposits the same amount of charge Qv on the hatchback car as it did on the van. Calculate the average electric field En newtons per coulomb, at the surface of the hatchback car.

Question

Part (a) Enter an expression for the electric flux De at the surface of the van in terms of the total charge on the van.

Use Gauss's law and the definition of electric flux to enter an expression for the average magnitude of the electric field Ey at the surface of the
van. Assume the electric field is constant over the surface of the van and let A represent the total surface area of the van. Your expression should be in terms of the total
charge on the van and the surface area.

Part (c) Assume the loose power line came to rest on a small hatchback car which has each of its three dimensions equal to exactly one half of the
dimensions of the van. The power line deposits the same amount of charge Qv on the hatchback car as it did on the van. Calculate the average electric field En
newtons per coulomb, at the surface of the hatchback car.

After a bad thunderstorm, a loose power line comes to rest on a parked van. The van is insulated from the ground by its tires, and accumulates an electric charge of Qy= 0.0023 coulombs from the loose power line. Treat the van as a conducting rectangular box with dimensions of Wy x L x Hy, where Wy = 1.80 m, L = 3.7 m, and Hv = 1.8 m. V
