An electron travels through a particular point in an experimental apparatus with a velocity of 0.822 10^6 m/s and at an angle of +68.2∘ (counter-clockwise) relative to the positive x-axis in the x-y plane. If the magnetic field at this point has a magnitude of 0.01 T and is directed in along the negative y-axis, what is the magnitude of the acceleration of the electron at this point? (It is advisable to sketch a picture of the situation first.)

A charged particle moves along the x-axis through a region with a uniform magnetic field that is oriented to lie in the x-y plane. Part a) Assume that the particle has a net charge of +669 μC and is moving with a velocity of 464 m/s in the +x direction at a particular instant. In that region of space, there is a uniform magnetic field of 1.91T directed in the x-y plane at an angle of +29.8 ∘ relative to...

A plane monochromatic radio wave (? = 0.3 m) travels in vacuum along the positive x-axis, with a time-averaged intensity I = 45.0 W/m2. Suppose at time t = 0, the electric field at the origin is measured to be directed along the positive y-axis with a magnitude equal to its maximum value. What is Bz, the magnetic field at the origin, at time t = 1.5 ns?

5. An electron carrying charge -9 (where q=1.602e-19 C) is moving along the x axis in the +x direction with a velocity ū(x, y, z) = 5 x 107 cm/s. a. We want to make the electron to curve to the right and eventually go in a circle clockwise in the xy plane by applying a magnetic field. To achieve that, the magnetic field should exert a force on the electron that is perpendicular to its direction of motion. Which...
