The hanging ball in each frame shown in the is stationary, explain why Next show that | cout| = mg tan theta Refer to Figure 4 below, and find the equation for tan theta as a function of x and L. Hint: Start by using the approximation for very small angles that tan 6 % sin 6 so then the lengths y and L can be assumed to be almost equal, provided that x ball L Combine the equations you derived in parts (c) and (d) to find the equation needed to calculate the experimentally determined magnitude of the Coulomb force as a function of L, x ball, m, and the local gravitational constant g.
