In the figure an electrically charged particle moves along a circle in a region of uniform magnetic field of magnitude B = 4.00mT. The particle is either a proton or an electron (you must decide which). It experiences a magnetic force of magnitude FB = 3.20 × 10-15 N.
Calculate:
a) the particle's speed.
b) the radius of the circle.
c) the period of the motion.
Two parallel, uniformly charged, infinitely long wires carry opposite charges with a linear charge density ? = 2.15 ?C/m and are 6.69 cm apart. What is the magnitude of the electric field at a point midway between them and 54.3 cm above the plane ..
