Physics WPH01: Electric Fields Topical Past Paper Questions

The photograph shows an arrangement for investigating charge, known as the “shuttling ball”. A ball coated in conducting material is suspended, on a very long insulating thread, between metal plates. A potential difference (p.d.) is applied across the plates so that plate X is po…

An electron travels through a uniform electric field for a time of $ 4.3 \times 10^{-9} $ s. It is deviated from its original path as shown. Calculate the deflection y of the electron. (4) electric field strength = $1.3 \times 10^{4} \mathrm{NC}^{-1}$

(a) Two point charges of $ 3.1 \times 10^{-9} C $ and $ -2.4 \times 10^{-8} C $ are placed a distance of 0.043 m apart in a vacuum. Calculate the magnitude of the force between the charges. Force = (b) The diagram represents the electric field around two point charges of equal ma…
