Suppose we suspend a negatively charged ball like a pendulum inside a hollow but completely enclosing metal box. Assume that the ball hangs a few inches from the box's left vertical face. Imagine that we now bring a very strong positively charged object to a point just to the left of the box's left face, so that it is only a few inches away from the suspended ball (though the box's left face is between them). The ball will be deflected strongly away from the external object. weakly toward the external object. not the least little bit. strongly toward the external object. weakly away from the external object.

A uniformly charged ring has a radius 130.cm and a charge 19.5 µC. A small object with mass 6.00 g and charge -0.100 µC is at the center of the ring, but it is free to move along the axis of the ring. (It is not free to move off the axis. Part A Suppose the small object is displaced along the axis a distance z from the center of the ring. It is only displaced a very small amount, so z is much smaller than the radius of the ring. Show that the force is roughly proportional to the displacement, that is, that F ≈ αz, and find a numerical value for α. √ AΣφ α = N/m Part B We see from Part A that for small displacements the force behaves like a spring with spring constant α. If the object is displaced a very small distance away along the axis, find the frequency f in Hz with which it oscillates back and forth. √ AΣφ ? f = HzA uniformly charged ring has a radius 130.cm and a charge 19.5 µC.

Consider a DRAM cell that uses an internal capacitor of 20 fF; it is charged to 3.3 V when storing a ' 1 '. In this problem, ignore body effect. (A real transistor like the access transistor here, or pass transistors in switch logic, can turn off before you want it to because of body effect; this one stays on until the 20 fF capacitor is fully charged. ) (6-points) (a) When writing a ' 1 ', how long does it take for the voltage on the capacitor to rise to 95% of its final value? Assume that when it is on, the access transistor in the cell has an average resistance of 6 kΩ; assume that the inverter driving the bit line has an average pull-up resistance of 1 kΩ. Ignore the resistance and capacitance of the bit line itself. (In a real memory, wire parasitics play a big role!)? (b) Suppose that when reading, the bit line is first charged to 3.3 V. The bit line is a large piece of metal, and has a total capacitance of 500 fF. How far does the bit line drop in voltage if a ' 0 ' is read? (Hint: In circuits, you learned that charge on capacitors in parallel redistributes until the voltage is equal; assume enough time is given for the bit line to drop as far as it ever will. )? (c) Suppose that the leakage current from the cell, due to the reverse-biased diode and subthreshold MOSFET currents, is no more than 2 pA. If a signal loss on the capacitor of 0.5 V can be tolerated, how often must the DRAM cell be refreshed to ensure that no data is lost?

A Geiger counter detects radiation such as alpha particles by using the fact that the radiation ionizes the air along its path. A thin wire lies on the axis of a hollow metal cylinder and is insulated from it (Figure 1). A large potential difference is established between the wire and the outer cylinder, with the wire at higher potential; this sets up a strong electric field directed radially outward. When ionizing radiation enters the device, it ionizes a few air molecules. The free electrons produced are accelerated by the electric field toward the wire and, on the way there, ionize many more air molecules. Thus a current pulse is produced that can be detected by appropriate electronic circuitry and converted to an audible "click." Suppose the radius of the central wire is 145 μm and the radius of the hollow cylinder is 1.80 cm. Part A What potential difference between the wire and the cylinder produces an electric field of 2.00×104 V/m at a distance of 1.20 cm from the axis of the wire? (Assume that the wire and cylinder are both very long in comparison to their radii.) Submit Request Answer Figure 1 of 1
