The potential energy of a one-dimensional mass m at a distance r from the origin is 􏰎􏰏 U(r)=U r +λ2R oRr for 0 < r < ∞, with Uo, R, and λ all positive constants. Find the equilibrium position ro. Let x be the distance from equilibrium and show that, for small x, the PE has the form U = const + 1 kx2. What is 2 the angular frequency of small oscillations?

Question 4. (Total 10 Marks) A D'Arsonval movement, or galvanometer (shown below in figure 4), is a very useful electro-mechanical device which lets you easily display small DC voltages and currents by the deflection of a pointer. Scale Moveable Pointer Coil Permanent Magnet Restoring Spring Magnetic Steel Core Figure 4. a) Explain how the deflection of a galvanometer's pointer is proportional to the current flowing through it. (3 Marks) b) One of the disadvantages of such a meter is that they are limited to displaying only small voltages and currents, with additional circuitry being required in order to display larger values. Given a galvanometer which can display a maximum of 1mA at full deflection and has an internal resistance of 5m$\Omega$, draw a simple circuit that would allow you to use this meter to measure from 0 to 10V. (3 Marks) c) Using the same meter as part (b), draw another circuit that will this time let you use the meter to measure up to 500mA (3 Marks) d) Why can these meters not be used (without modification) to measure AC voltages and currents? (1 Mark)
