A game is played using one die. If the die is rolled and shows 6, the player wins $20. If the die shows any number other than 6, the player wins nothing. Complete parts (a) through (b) below. a. If there is a charge of $4 to play the game, what is the game's expected value? $\boxed{\text{ }}$ (Round to the nearest cent.) b. What does this expected value mean? Choose the correct statement below. OA. This value represents the expected win over the long run for each game played. OB. The player can expect to break even over the long run. OC. This value represents the expected loss over the long run for each game played.

5. Electrodynamics: Consider Newton's 2nd Law "F = ma" with F = q(E+vxB) and acceleration\na = \frac{\partial v}{\partial t}, applied to a charged particle with mass m, charge q, velocity v. If E and B are constant (in\nspace and time) vector fields perpendicular to one another everywhere, then the solution of "F = ma"\nfor v will contain a zero-average time-varying "AC" component as well as a "DC" component. For\nsuch a field configuration:\na) Determine the DC component of the velocity v of the particle assuming that v has a zero\ncomponent parallel to B at t = 0. Hint: (1) DC component $v_{DC}$ of v will be independent of\ntime t in which case time average of "F = ma" reduces to E + $v_{DC}$ x B = 0 for the given fields.\n(2) you may need to use the vector identity A x (B x C) = (C \cdot A)B - (B \cdot A)C in order to\nsolve E + $v_{DC}$ x B = 0 for $v_{DC}$.\nb) What is $v_{DC}$ found in (a) explicitly if E = 2\hat{x} V/m and B = 1\hat{y} T?\nc) Bonus problem: How would the answer to parts (a) and (b) change if the particle had an\ninitial velocity v = 4B/|B| m/s at time t = 0 in the direction parallel to the magnetic field\nvector B? Justify your answer.\nd) Bonus problem: If an equal mix of positive and negative charge carriers per unit volume in\nthe region were to move with the steady-state velocities implied by the result of (a), would the\nresulting charge carrier motions in the mix produce a net current density J flowing perpendicular\nto the direction of B? Explain!\nNote: AC component of v for the situation described above will be examined in a separate HW\nproblem later on.
