E = σ/(2єₒ ) σ =4.70 * (10^ -6) , єₒ=8.854*(10^-12)
E= (4.70*10^ -6)/(2 x 8.85 X 10^-12) =0.265* 10^6= 265 kN/C

A very large (infinite area) flat nonconducting sheet has uniform charge per unit area sigma = 1.0 x 10^-5 C/m^2. B) Assume the equipotential surfaces are each in steps of 50V. what is the distance between two adjacent surfaces? (Hint: the units of electric field are V/m)
Two very large parallel plates have charge per unit area +1.5 μC/m2 and −1.5 μC/m2, respectively. A small grain of pollen of mass m = 235 mg and charge q hangs by a slender thread as shown in the figure below. If the thread makes an angle θ = 28° with the vertical direction, what is q?
Two very large parallel plates have charge per unit area +1.8 μC/m2 and −1.8 μC/m2, respectively. A small grain of pollen of mass m = 210 mg and charge q hangs by a slender thread as shown in the figure below. If the thread makes an angle θ = 33° with the vertical direction, what is q?
A very large, horizontal, nonconducting sheet of charge has uniform charge per unit area 9.00 × 10−6 C/m2. A small sphere of mass m = 4.00 × 10−6 kg and charge q is placed 3.00 cm above the sheet of charge and then released from rest. A) If the sphere is to remain motionless when it is released, what must be the value of q? Express your answer with the appropriate units. B) What is q if the sphere is...
