Bosons & Fermions A new type of quantum object has been discovered. When a large collection of these are cooled to almost absolute zero, they are observed to all condense into the same state - the ground state. Select all that are True.

Is this object a Fermion obeying Fermi-Dirac statistics?
Is this object a Boson obeying Bose-Einstein statistics?
Could this object have intrinsic spin 2 hbar?
Would the Schrodinger equation for two of these particles be symmetric with exchange of the two particles?
Could this object have intrinsic spin s = 3/2 hbar?
Would the Schrodinger equation for two of these particles be anti-symmetric with exchange of the two particles?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

Part f - example: finding two forces (part i) two dimensional dynamics often involves solving for two unknown quantities in two separate equations describing the total force. the block in (figure 1) has a mass m=10kg and is being pulled by a force f on a table with coefficient of static friction îľs=0.3. four forces act on it: the applied force f (directed î¸=30â above the horizontal). the force of gravity fg=mg (directly down, where g=9.8m/s2). the normal force n (directly up). the force of static friction fs (directly left, opposing any potential motion). if we want to find the size of the force necessary to just barely overcome static friction (in which case fs=îľsn), we use the condition that the sum of the forces in both directions must be 0. using some basic trigonometry, we can write this condition out for the forces in both the horizontal and vertical directions, respectively, as: fcosî¸â’îľsn=0 fsinî¸+nâ’mg=0 in order to find the magnitude of force f, we have to solve a system of two equations with both f and the normal force n unknown. use the methods we have learned to find an expression for f in terms of m, g, î¸, and îľs (no n).

Could someone me find the answer to this problem.
