A nonconducting, thin plane sheet of charge carries a uniform charge per unit area of 6.25 μC/m2 as in the figure below. Gaussian surface Gaussian (a) Find the electric field at a distance of 9.12 cm from the plate

Use the figure below. There is a point charge of 6.20 microCoulombs inside a spherical conducting shell with inner radius a=3.10 m and outer radius b=3.35 m. There is a total charge of  15.50 microCoulombs on the spherical shell.   What is the electric field at r=2.85 m from the point charge (ie inside the shell)? (Treat + as away from the point charge and negative as toward the point charge. Answer in N/C).

Imagine that in a region in space you detect a spherical symmetric electric field that increases quadratically with the distance from the center, E (r) = a · r2 . er, where a is a constant. How is the the charge distributed in that region, i.e. find p (r). increases linearly radially outward decreases linearly radially outward uniform

A electric field at 3.8 cm from the centre of a long copper rod of radius 0.7 cm has a magnitude 3.6 N/C and is directed outward from the axis of the rod. Part 1 What is the charge per unit length of the copper rod? = number (rtol=0.03, atol=0) C/m Part 2 What would be the electric flux through a cube of side 8.0 cm situated such that the rod passes through the opposite sides of the cube perpendicularly? number (rtol=0.03, atol=0) Nm?/C
