Question

The electric potential at x=3 m is 120 V, and the electric potential at x=5 m is 190 V. What is the x component of the electric field in this region, assuming the electric field is uniform? Select one: a. Zero b. 35 c. - 70 d. -35 e. - 140

Answer 1

Answer:

The electric potential at x = 3.00 m is 120V, and the electric potential at x =5.00 m is 190V. What is the x component of the electric field in this region, assuming the electric field is uniform?

I do the problem like this:

UE1=120V at 3m

UE2= 190V at 5m

ΔU=70V/2m=35V/m=35N/C

The answer given by Cramster Problem 4OQ Chapter 25 Physics For Scientists And Engineers with Modern Physics (8th) is -35 N/C.
