Question A very thin, finite, uniformly charged line of length 18 m carries a charge of 300 µC/m. Calculate the electric field intensity in a plane bisecting the line at p= 9 m. Question 3 A quarter-disc in the first quadrant has a surface charge density given by K cos o C/m2. If the radius of the disc is b, calculate the electric field at a point P(0,0,-h).
