Question Completion Status: QUESTION 1 Problem A new type of force was discovered by physicists with the following expression: a %3D Fnew=+Be*+ 3x where alpha & beta are constants, and x is the position. The expression above was obtained from the interaction ofa massless Higgs 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 = dx Evaluating the above, we get W= for the limits from xi to xf substituting x1 and x2 as the limits, the work done is expressed as | + B X1.

I Review Newton's law of gravity and Coulomb's law are both inverse-square laws. Consequently, there should be a "Gauss's law for gravity." Part A The electric field was defined as E = Fon g/g, and we used this to find the electric field of a point charge. Using analogous reasoning, what is the gravitational field g of a point mass? Write your answer using the unit vector r, but be careful with signs; the gravitational force between two "like masses" is attractive, not repulsive. Express your answer in terms of the variables M, r, unit vector î, and the gravitational constant G. Use the 'unit vector' button to denote unit vectors in your answer. • View Available Hint(s)

4. A student feels a gravity force of 800 N from the Earth when they're sitting in this classroom. a. How big is the gravity force that the Earth feels because of the student? Explain. b. Two students discuss part a) Student 1: "The Earth is much heavier than the student, so its gravity must pull harder on the student than the student's gravity pulls on the Earth. The gravity force the Earth feels must be less than 800 N." Student 2: "That might be true, but I think that same 800 N would have less of an effect on the Earth than it would on a person. Using a = F/m, the acceleration the Earth feels might be very small from an 800 N force, because Earth is so heavy." Which of these students, if any, do you agree with? Justify your response with words and/or equations.
