You have a lightweight spring whose unstretched length is 4.0 cm. First, you attach one end of the spring to the ceiling and hang a 2.2 g mass from it. This stretches the spring to a length of 5.2 cm. You then attach two small plastic beads to the opposite ends of the spring, lay the spring on a frictionless table, and give each plastic bead the same charge. This stretches the spring to a length of 4.5 cm. What is the magnitude of the charge (in nC) on each bead? Express your answer using two significant figures. ΤΗ ΑΣΦΑ ? at

- Two identical point charges (q = +1.00 x 10-6 C) are fixed at opposite corners of a square whose sides have a length of 0.420 m. A test charge (90 = -7.50 × 10-8 C), with a mass of 2.80 x 10-8 kg, is released from rest at one of the corners of the square. Determine the speed of the test charge when it reaches the center of the square. Number i Units .90 VB10 nC B. A -5 nC How much work must you do to move an electron from A to B? The rectangle is 14.6 cm high and 24.8 cm wide. Remember that negative work means that we can get work out of the process. In 1911, Ernest Rutherford and his assistants Geiger and Marsden conducted an experiment in which they scattered alpha particles (nuclei of helium atoms) from thin sheets of gold. An alpha particle, having charge +2e and mass 6.64 x 10-27 kg, is a product of certain radioactive decays. The results of the experiment led Rutherford to the idea that most of an atom's mass is in a very small nucleus, with electrons in orbit around it. Assume an alpha particle, initially very far from a stationary gold nucleus, is fired with a velocity of 2.98 × 107 m/s directly toward the nucleus (charge +79e). What is the smallest distance between the alpha particle and the nucleus before the alpha particle reverses direction? Assume the gold nucleus remains stationary. fmOne type of ink-jet printer, called an electrostatic ink-jet printer, forms the letters by using deflecting electrodes to steer charged ink drops up and down vertically as the ink jet sweeps horizontally across the page. The ink jet forms 35.0 μm-diameter drops of ink, charges them by spraying 800,000 electrons on the surface, and shoots them toward the page with a horizontal velocity of 17.0 m/s. Along the way, the drops pass through the long axis of two horizontal, parallel electrodes that are 6.0 mm long, 4.0 mm wide, and spaced 1.0 mm apart. The distance from the center of the electrodes to the paper is 1.90 cm. To form the letters, which have a maximum height of 6.0 mm, the drops need to be deflected up or down a maximum of 3.0 mm. Ink, which consists of dye particles suspended in alcohol, has a density of 800 kg/m³. 3 E D 80 C $ 4 R 888 F4 F V % 5 FS T ^ G 6 B Part A What electric field strength is needed between the electrodes to achieve this deflection?

- We assemble a group of three charges, each of + 2.0 µC, bringing them in from infinite distance, where we set V = 0. We put the first charge at x = 0 cm, then put the second one at x = 10 cm, and last put the third one at x = 20 cm. What was the total work done by the applied force? (Hint: At each step, W_applied = + Delta(PE) = + q Delta(V), where q is the charge you're bringing in now and V is determined by the charges that are already in place.)THE FIGURE BELOW SHOWS A CROSS SECTION OF TWO LONG, THIN COAXIAL CYLINDERS OF RADIUS a AND b.

- A particle (charge= 2.1x10^-6 C) is released from rest at a point x=10.1 cm. If a 42.3x10^-6 C charge is held fixed at the origin, what is the kinetic energy of the particle after it has moved 92.8 cm?You and your colleagues have been tasked with launching a weather balloon into the Earth's stratosphere via rocket ship. In order to reduce fuel usage to meet with newly imposed fuel-consumption regulations, you are hoping to use the electric interaction between charges to your advantage. You have decided on the design below. You are able to place two Q = 1.98 C charges in the rocket ship and into the launching platform so that they are separated by a distance of yo = 2.93 m. You are allowed enough fuel to boost the rocket to an initial speed of vo = 309 m/s without accounting for the extra boost from the charges. The rocket on its own has a mass of 2.095x104 kg. The more equipment you can attach to your weather balloon (which is inside the rocket), the better. What limit do you put on the mass of the weather balloon and attached equipment? You may want to know the formula for gravitational potential energy for an object of mass m and height h: Egray = mgh, where g=9.81 m/s?. Edge of…
