The expression above was obtained from the interaction of a massless Higg s Boson (a type of particle) and a black hole. Quantum physicists then decides to design and build a machine that is able to move the Higgs Boson from x2 to x1. How much work should the machine do to achieve this feat? (For simplicity, consider that no energy is lost in the process) Solution To determine the work done we apply the following W = Fx dx Evaluating the above, we get W = aln | x beta e X 3/5 5 for the limits from x¡ to xf substituting x1 and x2 as the limits, the work done is expressed as W = | + X1 e ( x15 x2 ) x2 MacBook Proarrow_forwardIn a laboratory experiment, an electron with a kinetic energy of 50.5 keV is shot toward another electron initially at rest (Fig. P11.50).
