A very large (can be considered infinite) plastic sheet is uniformly charged. The charge in 1.00 m2 area of the sheet is Incasured to be 4.71 E-6 C. What is the electric field magnitude at a point 2.14B-2 m away from the sheet (answer a positive number in N/C)? Physics constants: Number = = 3.14 Coulomb constant k = 1/(476) = 8.99E9 N•m/C2 Permittivity of vacuum &g = 8.85B-12

A single isolated, large conducting plate has acharge per unit area σ on its surface. Because the plate is a conductor, the electric field at its surface is perpendicular to the surface and has magnitude E = σ/εo a.The field from a large, uniformly charged sheet with charge per unit area σ has magnitude E = σ/2εo. Why is there a difference? b.Regard the charge distribution on the conducting plate as two sheets of charge (one on each surface), each with charge per unit area σ. Find the electric field inside and outside the plate.

A 0.4 g object is placed in a 449 N/C uniform electric field. Upon being released from rest, it moves 62 m in 1.8 s. Determine the object's acceleration & charge magnitude. Assume the acceleration is due to the E-field (i.e., ignore all other forces). a = Q =
