Question

An electron enters a chamber in which a uniform magnetic field is present as shown

Chamber of uniform magnetic field

Chamber of Uniform Magnetic Field

In figure direction of the uniform magnetic field in the chamber and direction of the electron enter in the chamber are shown.

An electric field of appropriate magnitude is also applied so that the electron travels undeviated without any change in its speed through the chamber. We are ignoring gravity. Then, the direction of the electric field is,
