- #16 Infinite Line Charge What is the electric field strength 0.123 m from an infinite line charge with a linear charge density A of 2.12 × 10-5 C/m? A. 310,000 N/C B. 450,000 N/C C. 620,000 N/C D. 950,000 N/CUnreasonable ResultsA wrecking yard inventor wants to pick up cars by charging a 0.400 m diameter ball and inducing an equal and opposite charge on the car. If a car has a 1000 kg mass and the ball is to be able to lift it from a distance of1.00 m: (a) What minimum charge must be used? (b) What is the electric field near the surface of the ball? (c) Why are these results unreasonable? (d) Which premise or assumption is responsible?2- A non-conductive wall of uniform charge has a charge density of 8.6 µc / cm?.What is the magnitude of the electric field at a point facing the wall
- 5- prove that F(x, y, z) = (3x² + y)i + 2xyj – 3z2k is a conserved field. %3D2. What happens then, if we had a collection ofn equally and positive charges? Write down the definition of what an electric field would be for n equally distant charges. What can we say about the difference between discrete and continuous charges? What are the different types of uniform charge distributions? + 43 Determine the net electric field on q5 given equally placed charges as shown by writing the expression in terms of vector components for some distance between each charge rı = r3 and r2 respectively.. Where is the electric field point?4. Determine the equation for the electric field at the origin caused by a surface charge distribution with density Ps = cose located on the surface of a sphere at radius = 2m. It would be wise for you to consider the symmetry of the problem, such that only the z-component is non-zero. The x and y component should cancel out (convince yourself of this!).
