1) An electron enters the space between two parallel charged plates with an initial velocity u.

While in the electric field, its direction changes by θ and it emerges with a velocity v. What is the relation between v and u?

2) The diagram shows an insulating rod with equal and opposite point charges at each end.

An electric field of strength E acts on the rod in a downwards direction.

Which row is correct?

3) The diagram shows an electron, with charge q, mass m, and velocity v, entering a uniform electric field of strength E.

The direction of the field and the electron's motion are both horizontal and to the right.

Which expression gives the distance x through which the electron travels before it stops momentarily?

4) The electric field at a certain distance from an isolated alpha particle is 3.0 × 10⁷ N C^–1.

What is the force on an electron when at that distance from the alpha particle?

Take the magnitude of the charge of the electron to be 1.60 × 10⁻¹⁹ C.

5) The diagram shows an electron in a uniform electric field.

In which direction will the field accelerate the electron?
