Answer:
∆V= -400 Volts
Explanation:
xi= 10 cm= 0.1 m
xf= 30 cm = 0.3 m
E= 2000 V/m
We have the equation
∆V=-E (∆d)= E (xf -xi)
∆V=-2000V/m (0.3 -0.1)m
∆V= -400 Volts
The potential difference is [tex]-400V/m[/tex]
The potential difference is given as,
[tex]\Delta V=-E( x_{f}-x_{i})[/tex]
Where E is electric field , [tex]x_{f}[/tex] and [tex]x_{i}[/tex] are final and initial position.
Given that, [tex]E=2000V/m,x_{f}=30cm=0.3m,x_{i}=10cm=0.1m[/tex]
Substitute values in above relation.
[tex]\Delta V=-2000( 0.3-0.1)\\\\\Delta V=-2000*0.2=-400V/m[/tex]
