A because 1.6 is less than 2.4, 2.2, and 2.6
Answer:

Step-by-step explanation:
The potential in a region between x = 0 and x = 6.00 m is V = a + bx.
Put a = 15.4 V and b = -5.10 V/m.
So, 
To find: Potential at x =0, 3, 6
Solution:
Potential at x = 0:

Potential at x = 3:

Potential at x = 6:

Therefore,

<span>a^3 - b^2 for a = 3 and b = 1/2
</span>3^3 - (1/2)^2
= 27 - 1/4
= 26 3/4
Sis, I think its c. Correct me if i'm wrong, hope I helped you!
Less. The distance across the field is less than 20 km
