QUESTION:
A long line carrying a uniform linear charge density +50.0 µC/m runs parallel to and 10.0 cm from the surface of a large, flat plastic sheet that has a uniform surface charge density of -100 µC/m2 on one side. Find the location of all points where an ? particle would feel no force due to this arrangement of charged objects.
ANSWER:Introduction We have to calculate the point where the electric field will be zero. Step 1 The electric field at a distancis given by Where is the linear charge density. Now the electric field due uniformly charged infinite sheet at a distancefrom the sheet is given by Here is the surface charge density.
