What is the potential difference
between xi = ?10cm
and xf =
60cm?
The electric field in a region of space is Ex
=-1700 xV/m, where x is in meters.
E? = -1700 V/m
Potential at x?, V? = -10cm = -0.1 m
V1 = (-1700)(-0.1) = 170 V
Potential at x?, V? = 60cm = 0.6 m
V2 = (-1700)(0.6) = -1020 V
Potential Difference = V2 - V1
= -1020 - (170)
= -1190 V.
