IB Physics HL D.2.9 Parallel-Plate Field Question Bank

Practise IB Physics HL D.2.9 by solving parallel-plate field, potential, capacitor and charged-particle equilibrium problems.

[Maximum number: 1]

Two oppositely charged parallel plates are a distance 8.0 cm apart. The potential difference between the plates is 120 V . An alpha particle is placed on the positively charged plate and released from rest. Gravity is ignored.

Calculate the electric field between the plates.

$E=<\frac{120}{8.0 \times 10^{-2}}=>1.5 \times 10^{3} N C^{-1} \boldsymbol{O} \boldsymbol{R} \mathrm{Vm}^{-1}$
