Chapter 16: Q7CP (page 639)

You travel along a path from location A to location B, moving in a direction perpendicular to the direction of the net electric field in that region.

What is true of the potential difference VB-VA?

(1)VB-VA>0,(2)VB-VA<0(3)VB-VA=0

Short Answer

Expert verified

VB-VA<0,is the correct option.

Step by step solution

01

Potential difference.

The difference of electrical potential between two points.

V=IR

02

Solution.

You travel along a path from location A to location B, moving in a direction perpendicular to the direction of the net electric field in that region,. Here the diagram define this statement more clearly,

Electric field from AtoB.

VB-VA=-Vebecause, It goes to electric field always goes higher potential to lower potential. but, VBtoVAis the opposite direction.

Hence option 鈥渂鈥� ,VB-VA<0, is the correct option.

Most popular questions from this chapter

An isolated parallel-plate capacitor of area \({A_1}\) with an air gap of length \({s_1}\) is charged up to a potential difference\(\Delta {V_1}\). A second parallel-plate capacitor, initially uncharged, has an area \({A_2}\) and a gap of length \({s_2}\)filled with plastic whose dielectric constant is\(K\). You connect a wire from the positive plate of the first capacitor to one of the second capacitor, and you connect another wire from the negative plate of the first capacitor to the other plate of the second capacitor. What is the final potential difference across the first capacitor?

What is the potential at the centre of a spherical shell ofradius Rthat has a charge Quniformly distributed over its surface? Don鈥檛 do an integral of the electric field; just add up the contributions to the potential by the charges.

A capacitor with a gap of 1mm has a potential difference from one plate to the other of36V . What is the magnitude of the electric field between the plates?

What is the potential (relative to infinity) at location B, a distance h from a ring of radius a with charge 鈥換 as shown in figure 16.94?

The diagram in Figure 16.74 shows three very large metal disks (seen edgewise), carrying charges as indicated. On each surface the charges are distributed approximately uniformly. Each disk has a very large radius R and a small thickness t. The distances between the disks are a and b, as shown; they also are small compared to R. Calculate V2-V1, and explain your calculation briefly.
