Question

A charge is released from rest in a

uniform electric field with a magnitude of 4.5 × 10^3 V/m. The charge moves 350 cm as aresult. What is the potential difference between the charge’s initial and final positions?

Answer 1

the potential difference between the initial and final positions of the charge is

$\Delta\phi=\Epsilon \cdot \Delta S=4.5 \cdot 10 ^3\cdot 0.35=1575 V$
