A small positively charged plastic ball of mass m and charge q is suspended by a massless string of length L in a uniform electrical field E as shown in the attached image. The ball is in equilibrium when the string makes an angle of θ with the vertical. Note that the ball is under the influence of both the electric field E and the earth's gravitational force g. a. Write an equation for the horizontal electrical force acting on the ball in terms of the relevant variables provided above b. Write an equation for the tension T in the string, using any or all of the relevant variables provided above and/or any relevant constants (g, G, k).

Imagine that you are given a box which is said to be filled with various charged objects. You cannot open the box but are tasked with determining what could possibly be inside of it. Q2: If you can measure the electric field at a point in space then you can estimate the symmetry of the charge distribution inside of the box. For spherical, cylindrical, and planar symmetry provide a diagram of the expected electric field lines around the box for each situation. Using fundamentals of static electric fields explain the shapes of the field lines in each situation. Indicate quantitatively how the magnitude of the field changes as you move away from the box Q3: Since the box has finite size, describe how the field lines in each case outlined in question 2 would differ from their idealized charge distribution. For all three situations, what would the charge distribution look like when you move far away from the box?
