One electron collides elastically with a second electron initially at rest. After the collision, the radii of their trajectories are r1 and r2. The trajectories are perpendicular to a uniform magnetic field of magnitude
Determine the energy of the incident electron. (Use any variable or symbol stated above along with the following as necessary: me for the mass of elecron and e for the electron's charge.)
At a certain point on Earth's surface in the southern hemisphere, the magnetic field has a magnitude of 5.1 10-5 T, find the magnitude and direction of the force on the muon
Consider a line that is 1.4 m long. A moving object is somewhere along this line, but its position is not known. Find the minimum uncertainty in the momentum of the object
A 67 kg person sits on a 3.5kg chair. Each leg of the chair makes contact with the floor in a circle that is 1.8 cm in diam. Determine the pressure exerted on the floor by each leg of the chair; Assume the weight is evenly distributed.
A 3m long ladder leans against a frictionless wall. The coefficent of static friction between teh ladder and the floor is .40. What is the minimum angle the ladder can make
