Apositively charged particle of mass is traveling due east with a speed of and enters a uniform magnetic field. the particle moves through one-quarter of a circle in a time of at which time it leaves the field heading due south. all during the motion the particle moves perpendicular to the magnetic field. (a) what is the magnitude of the magnetic force acting on the particle? (b) determine the magnitude of its charge.

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
