#2 (a) The fundamental SI units are meters for length, seconds for time, kilograms for mass, andCoulomb for charge. Use the Coulomb force law for two interacting point charges (F = kq1q2/r2)and the force units you already know from mechanics (N) to find the SI units for Coulomb’sconstant k and the constant 0 = 1/4πk. Express your answers using only the four fundamentalunits. (b) What are the units of the electric field, expressed first using force units (N) and then using onlyfundamental SI units? (c) Visualizing how an electric field varies with location is going to prove very helpful. Using arrowsat several test points in the xy plane - enough points to illustrate the behavior of the fields -sketch the following electric fields at the test points and briefly describe the behavior of the fieldin words. You only need to provide a qualitatively correct plot that is consistent with the vectorfunction and the description - you don’t need to calculate the vectors although I will show…

An alpha particle (charge +3.20 x 10-19C, mass 6.64 x 10-27kg) is initially 5.2 cm away from a fixed gold nucleus (charge +1.26 x 10-17C, mass 3.29 x 10-25kg) and moving toward the nucleus with a speed of 8.1 x 105m/s. How close to the nucleus does the alpha particle get? (Note: The nucleus diameter is approximately 10-14m and the and alpha particle’s is 10-15m.)
Millikan measured the electron's charge by observing tiny charged oil drops in an electric field. Each drop had a charge imbalance of only a few electrons. The strength of the electric field was adjusted so that the electric and gravitational forces on a drop would balance and the drop would be suspended in air. In this way the charge on the drop could be calculated. The charge was always found to be a small multiple of 1.6e-19 C. Find the charge on an oil drop weighing 3.34 10-14 N and suspended in a downward field of magnitude 2.98 104 N/C.

simple and common technique for accelerating electrons is shown in the figure below, where there is a uniform electric field between two plates © L 39% Electrons are released, usually from a hot filament, near the negative plate, and there is a small hole in the positive plate that allows the electrons to continue moving. (a) Calculate the acceleration in meters per second squared of the electron if the field strength is 3.20 x104 N/C. m/s2 (b) Explain why the electron will not be pulled back to the positive plate once it moves through the hole.

Use the following constants if necessary. Coulomb constant, k = 8.987 x 10° N m2 /C. Vacuum permitivity, eo = 8.854 x 10 12 F/m. Magnitude of the Charge of one electron, e =-1.60217662 x 10-19 C. Mass of one electron, m, = 9.10938356 x 10-31 kg. Unless specified otherwise, each symbol carries their usual meaning. For example, uC means micro coulomb. Y R. Suppose you have 5 point charges q to q, distributed along a semi-circle maintaining equal distance. The charge q6 is on the center of the circle which is also the origin of given coordinate system. The radius of the semi-circle is R = 34 cm and the magnitude of the charges are as follows : 91 = = 19 µC, q2 = q4 = 32 µC and q = q6 = -25 µC. a) Find the vector that points from q to g6 and call it F1,6- b) Calculate the coulomb force on g6 due to q in unit vector notation and call it F16 c) Find the vector that points from q3 to g6 and call it F3,6- d) Calculate the coulomb force on q6 due to g in unit vector notation and call it F36. e)…
Coulomb’s law tells us that the electrostatic force between two charged objects can be calculated by: ?= ??1?2/?^2Where k is a constant with a value of 8.99x109 Nm2/C2; ?1 and ?2 are the charges of the two particles (1.602x10-19 C), and r is the distance between the two particles. The force is attractive if the charges of the two particles is opposite (one’s positive and one’s negative) and repulsive if the charges have the same charge (both positive or both negative). Calculate the electrostatic force on proton #1 from the other two protons.Will the gravitational force between the protons be attractive or repulsive? What about the electrostatic force? Which has the larger magnitude, the electrostatic force or the gravitational force? Can the electrostatic and gravitational forces alone create a stable Lithium nucleus?
