Explanation / Answer

Here ,

Em = 20 N/C

Vo = 12 V

a) at the point x = 2 m

Vf - Vo = - (- 0.5 * 2 * 20)

Vf = 12 + 20 = 32 V

the potential at x = 2 is 32 V

b)

electric field is maximum at x = 3 m

Vf - Vo = - (- 0.5 * 3 * 20)

Vf = 12 + 30 = 42 V

the potential at x = 2 is 42 V

c) for the value of potential to bbe zero

0 = 12 - (- 0.5 * 3 * 20) - 0.5 * 20 * 1 - 20 * (x - 4)

solving for x

x = 5.6 m

the potential is zero at x = 5.6 m
