particle that carries a net charge of-41.8 LC is held in a region of constant, uniform electric field. The electric field vector is oriented 25.2° clockwise from the vertical axis, as shown. If the magnitude of the electric field is 4.32 N/C how much work is done by the electric field as the particle is made to move a distance of d 0.956 m straight up? Incorrect. The angle involved in the work calculation should represent the angle between the...
Velocity Selector-multiple choice
The Velocity SelectorIn experiments where all the charged particles in a beam are required to have the same velocity (for example, when entering a mass spectrometer), scientists use a velocity selector. A velocity selector has a region of uniform electric and magnetic fields that are perpendicular to each other and perpendicular to the motion of the charged particles. Both the electric and magnetic fields exert a force on the charged particles. If a particle has precisely the right velocity, the...

In the figure, an electron with an initial kinetic energy of
3.50 keV enters region 1 at time t = 0. That region contains a
uniform magnetic field directed into the page, with magnitude
0.00910 T. The electron goes through a half-circle and then exits
region 1, headed toward region 2 across a gap of 22.0 cm. There is
an electric potential difference ?V = 2000 V across the gap, with a
polarity such that the electron's speed increases uniformly...
