3. A circular loop of thin wire, radius a, carries uniform positive charge density. Determine the instantaneous force on a negative charge released at a distance z << a along the axis of the loop and show that this charge will oscillate about the centre of the loop. Calculate the frequency of oscillation. Hint: First calculate the electric field at the point in question, and determine the equation of motion of the negative charge (Newton's second law).

1. A very large flat insulating sheet with uniform charge per area n (SI units: C/m²) sits in the y-z plane at x = 0. We want to find the electric field at a point Pa distance x from the sheet. Assume P is far from the edges and x is small compared to the size of the sheet. Assume that is positive. From symmetry, the electric field must point directly away from the sheet. We choose to draw the Gaussian surface as a cylinder of radius R that extends a distance x on both sides of the sheet. а. Which statement is true regarding the flux through the Gaussian surface? Choose one answer below! The electric flux through all the surfaces is zero. The flux through the endcaps is zero and the flux through the curved section is positive. The flux through the endcaps is zero and the flux through the curved section is negative. R The flux through the curved section is zero. The flux through the right endcaps is positive and through the left endcaps is negative. The flux through the curved section…
