Aparticle with negative charge q and mass m = 2.65×10−15 kg is traveling through a region containing a uniform magnetic field b⃗ =(− 0.130t) k^. at a particular instant of time the velocity of the particle is v⃗ =(1.20 × 106 m/s) (−3i^ + 4j^+12 k^) and the force f⃗ on the particle has a magnitude of 2.30 n . (a) determine the charge q. (b) determine the acceleration a⃗ of the particle. (c) find the x, y and z-component of the acceleration

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
