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.
