Assuming the radius of the circular path of the electron is 4.9cm when voltage is 100v and coil current is 1.4 A and The Helmholtz coils have 130 turns and a radius of 15 cm. With N=130 and R=0.15 If the current in the Helmholtz coils were 1.4 A, rather than 1 A, and the accelerating voltage were still 100 V, what would the radius of the electron's path be? Give your answer in cm, and enter only the number. Blackboard will accept an answer witin 20% of the value it expects.
What is the speed of a beam of electrons (in SI units) that go undeflected when passing through crossed electric and magnetic fields of magnitude (5.07x10^0)x104 V/m and (4.270x10^0)x10-3 T, respectively? Give your answer to 3 sf.
Albert Einstein is pondering how to write his (soonto-be-famous) equation. He knows that energy E is a function of mass m and the speed of light c, but he doesn't know the functional relationship (E = m2c? E = mc4?). Pretend that Albert knows nothing about dimensional analysis, but since you are taking a fluid mechanics class, you help Albert come up with his equation. Use the step-by-step method of repeating variables to generate a dimensionless relationship between these parameters, showing all of your work. Compare this to Einstein's famous equation—does dimensional analysis give you the correct form of the equation?
Using the given charge-to-mass ratios for electrons and protons, and knowing the magnitudes of their charges are equal, what is the ratio of the proton's mass to the electron's? (The charge-to-mass ratios for electrons and protons are −1.7588×1011 C/kg and 9.5788e7 C/kg , respectively. Note that since the charge-to-mass ratios are given to five-digit accuracy, your answer may differ from the accepted ratio. Round your answer to at least five significant figures.) Mp/Me =

If a proton and electron are released when they are 2.0 m apart, find the initial acceleration of electron (in m/s2). The answer (in fundamental SI unit) is ___________ (type the numeric value only)
Consider a model of an electron as a hollow sphere with radius R and the electron charge -e spread uniformly over that surface. d. Use Einstein’s equation relating rest mass to energy to derive a value for R. Unfortunately, your answer will be model-dependent. The traditional “Classical radius of the electron” is derived by setting the electrostatic work to be e2/(4pi e0 R)
Suppose we have a charge, q1=1 μC. This charge makes an electric field some distance r=60 cm away from it. Now suppose our measurement of q1 is only accurate to within 0.1 μC, and our measurement of r is only accurate to within 2 cm. What is the uncertainty in our field calculation due only to the uncertainty in the charge separation r? for the uncertainty of q I got 2500 N/C. I keep getting 1667.67 N/C for the uncertainty for the separation of r but that is wrong
