Electric field intensity Definition and 53 Threads

Hi, I would appreciate is someone could help me figure out this problem: The electric Field Intensity in free space from a very long, uniformly charged cylinder of radius 5cm is 100 kV/m at a radius of 1m. What must be the surface charge density on the cylinder? I've tried using different...

A uniformly charged wire with a charge density of p (rho) extends along the z-axis from z = 0 to z =+ infinity. Determine the electric field intensity at a point P (rho, phi, 0) Ok so I wrote down the equation for electric field intensity for a uniformly charged wire ie E=k[integral of...

Quick Physics Help... X and Z represent point charges of -2.4 x 10^-3 C and +3.3 x 10^-2 C respectively. Calculate the magnitude and direction of the electric field intensity at point Y, 5.00 cm from X and 8.50 cm from Z (they all live in a line). Can sumone help me?
