Force Acting on Moving Charges: Practice Problem & Solution

An electron moves in the plane of the page through two regions of space along the dotted-line trajectory shown in the figure. There is a uniform electric field in Region-I directed into the plane of the page (as shown). There is no electric field in Region-II. What is a necessary direction of the magnetic field in regions I and II ? Ignore gravitational forces. Force Acting on Moving Charges diagram: An electron moves in the plane of the
Region-I Down the plane of the page Region-II Up the plane of the page
Region-I  Up the plane of the page Region-II Into the plane of the page
Region-I  Up the plane of the page  Region-II Out of the plane of the page
Region-I  Down the plane of the page  Region-II Out of the plane of the page

A charge \( q = 1.6 \times 10^{-12} \text{ C} \) moving with speed of \( v \text{ m s}^{-1} \) crosses electric field \( |\vec{E}| = 6 \times 10^4 \text{ V m}^{-1} \) and magnetic field \( |\vec{B}| = 1.2 \text{ T} \). The electric field and magnetic fields are crossed and velocity \( v \) is also perpendicular to both. If the charge particle crosses both fields undeflected, the value of \( v \) is
5. Two very long straight parallel wires carry steady currents i and 2i in opposite directions. The distance between the wires is d. At a certain instant of time a point charge q is at a point equidistant from the two wires in the plane of the wires. Its instantaneous velocity \(\overrightarrow{v}\) is perpendicular to this plane. The magnitude of the force due to the magnetic field acting on the charge at this instant is :
