A particle (mass = 6.0 mg) moves with a speed of 4.0 km/s in a direction that makes an angle of 37 ∘ above the positive x axis in the xy plane. At the instant it enters a magnetic field of (5.0 ^ i )mT it experiences an acceleration of (8.0 ^ k ) m / s 2 . What is the charge of the particle?

A beam of electrons whose kinetic energy is K emerges from a thin-foil window at the end of an accelerator tube. A metal plate at distance d from this window is perpendicular to the direction of the emerging beam (see figure). We can prevent the beam from hitting the plate if we apply a uniform magnetic field such that B≥e 2 d 2 2 mK in which m and e are the electron mass and charge. How should B be oriented?

An electron with kinetic energy 2.5 ke V moving along the positive direction of an x axis enters a region in which a uniform electric field of magnitude 10 k V/m is in the negative direction of the y-axis. A uniform magnetic field B→ is to be set up to keep the electron moving along the x-axis , and the direction B→ of is to be chosen to minimize the required magnitude of B. In unit-vector notation, what B should be set up?
