22-78

Two infinite uniformly charged, flat, nonconducting surfaces are i ua perpendicular. One of the surfaces has a charge distribution of +3 0.0 pC/nr, and the other has a charge distribution of-40.0 pC/m2. What is the magnitude of the electric field at any point not on either surface? There is an electric field of magnitude 150. N/C, directed vertically downward, near the surface of the Earth. Find the acceleration (magnitude and direction) of an electron released near the Earths surface. Suppose you have a large spherical balloon and you are able to measure the component En of the electric field normal to its surface. It you sum En dA over the whole surface area of the balloon and obtain a magnitude Q1 N m2/C, what is the electric charge enclosed by the balloon?

Explanation / Answer

applying gauss law

Electric flux= Qin/abselon

so Qin=10*8.85*10^-12 C

so Qin= 8.85*10^-11 C
