Question

A uniform electric field of 23 N/C is directed in -y direction. If one moves 0.45 meters in the +y direction, what is the change in electric potential in volts? If answer is negative, include a negative sign.

Answer 1

The change in electric potential in a uniform electric field is given by:

∆V = -E×∆d

Where 'd' is distance moved in the direction of electric field.

So putting values,

E = 23 N/C

∆d = - 0.45 m (∆d is negative because we move opposite to direction of electric field)

Hence, change in voltage is,

V = -23 × -0.45 = 10.35 V

V = 10.35 V
