CAIE A-Level Physics AS 9.2.2 V W Q Questions question 1
Two vertical metal plates are separated by a distance d in a vacuum, as shown in Fig. 7.1.
Fig. 7.1 (not to scale)
The potential difference (p.d.) between the plates is V. A nucleus with charge +q is initially at rest on plate X . The nucleus is accelerated by the uniform electric field from plate X along a horizontal path to plate Y .
State expressions, in terms of some or all of d, q and V, for:
the kinetic energy of the nucleus when it reaches plate Y .
kinetic energy =
