A uniform electric field E = 3250 V/m exists within a certain region. What volume of space contains an energy equal to 1.10 x 107 3? Express your answer in cubic meters and in liters. 2.4609E-3 X Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. m³ 2.46 x Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. L

Given the mass of the hydrogen ion to be 1.67 × 10-27 kg (same as a proton), solve the following problems.  Enter an expression for the ratio of the final speed of an electron to that of a negative hydrogen ion (one having an extra electron), both accelerated through the same voltage from rest, assuming non-relativistic final speeds. ve/vH = Calculate the value of the ratio you found in part (b).

The voltage across a membrane forming a cell wall is 77.7 mV and the membrane is 9.02 nm thick. What is the electric field strength? (The value is surprisingly large, but correct.) You may assume a uniform E-field.

An electron is fired at a speed vi = 4.3 × 106 m/s and at an angle θi = 39.7° between two parallel conducting plates as shown in the figure. If s = 1.7 mm and the voltage difference between the plates is ΔV = 99.8 V, determine how close, w, the electron will get to the bottom plate. Put your answer in meters and include at 6 decimal places in your answer. Do not include units. The x-axis of the coordinate system is in the middle of the parallel plate capacitor.   Round your answer to 6 decimal places.

An electron is fired at a speed vi = 3.1 × 106 m/s and at an angle θi = 36.8° between two parallel conducting plates as shown in the figure. If s = 1.8 mm and the voltage difference between the plates is ΔV = 98.8 V, determine how close, w, the electron will get to the bottom plate. Put your answer in meters and include at 6 decimal places in your answer. Do not include units. The x-axis of the coordinate system is in the middle of the parallel plate capacitor

6. The radius of the central wire of a Geiger counter is (a – 200 um) and the radius of the hollow cylinder is (b – 2.50 cm). What potential difference between the wire and the cylinder produces an electric field of (E – 3.00 x 104 V/m) at a distance of (r – 2.00 cm) from the axis of the wire? First derive theoretically the potential of the inner wire with respect to the outer cylinder.

You are working in a laboratory, using very sensitive measurement equipment. Your supervisor has explained that the equipment is also very sensitive to electrical discharge from human operators. Specification tables for the equipment indicate that an electrical discharge providing even a very small amount of energy of 250 μJ is enough to damage the equipment. Your supervisor wants to install an apparatus that will be used to remove the electrical charge from individuals’ bodies before they touch the equipment. To do this, she asks you to estimate (a) the capacitance of the human body and determine (b) the charge on the body and (c) the electric potential of the body, relative to a point infinitely far away, corresponding to the energy transfer that will damage the equipment.

In a Millikan oil-drop experiment, a uniform electric field of 6.66 x 105 N/C is maintained in the region between two plates separated by 1.31 cm. Find the potential difference between the plates. MI Number i Units

WORK, ENERGY POWER P CA 0.2793 kg rocket in a fireworks display is launched from rest and follows an erratic flight path to reach the point P. Point P is 29 m above the starting point. In the process, 400 J of work is done on the rocket by the nonconservative force generated by the burning propellant. Ignoring air resistance and the mass lost due 29 m he Vo = 0 m/s to the burning propellant, find the speed vf of the rocket at the point P. ho
