As an example of the manipulation of an electron beam, consider an electron traveling away from the origin along the x axis in the xy plane with initial velocity v1 = viî. as it passes through the region x = 0 to x = d, the electron experiences acceleration a = axî + ayĵ, where ax and ay are constants. for the case vi = 1.66 ✕ 107 m/s, ax = 7.37 ✕ 1014 m/s2, and ay = 1.78 ✕ 1015 m/s2, determine the following at x = d = 0.0100 m.

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
