A proton, a neutron (q=+e, m = 2u) and an alpha particle (q=+2e, m = 4u), accelerated through the same potential difference, enter a region of uniform magnetic field, moving perpendicular to B. Compare their kinetic energies. If the radii of the proton's circular path is 10cm, what are the radii of the deutron's path and the alpha particle's path? u is the atomic mass unit.
What is the moment of inertia relative to the center of mass of a 25.0 kg hoop with a radius of 2.0m
Speedboat A negotiates a curve whose radius is 150 m. Speedboat B negotiates a curve whose radius is 190 m. Each boat experiences the same centripetal acceleration. What is the ratio vA/vB of the speeds of boats.
A space shuttle, in a 300km high orbit, releases a 100 kg payload attached by a 10 km long massless rope. Assuming initial motions of lowering payload have damped out and the shuttle and payload are flying in steady state conditions.
A uniform electric field with a magnitude of 5550N/C points in the positive x direction. Find the change in electric potential energy when a +16.5-μC charge is moved 5.50cm in the positive x direction
