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,

Answer:
16

Answer:
Without a [roblem to go along with x=4, this would be underfined
Step-by-step explanation:
The side is 3 so it would be 3 times 5, your answer is 15
