Chapter 4: Q22DQ (page 713)

The electric fields at pointdueto the positive chargesandare shown

in Fig. Q21.22. Does the fact that theycross each other violate the statement in

Section 21.6 that electric field lines nevercross? Explain.

Short Answer

Expert verified

Answer

The electric lines that represent the field cannot cross at any given point in space. Of fact, that is not the situation here as the two lines come from two distinct places.

Step by step solution

01

Definition of the electric field

An electric field is an electrical feature correlated with each location in space where charge exists in any form. The value of E represents the size and location of the electric field.

02

Determines how strong the field must be to make this happen

Electric field linesare imaginary lines that represent the strength and direction of an electric field at a certain location in space.

Two electric fields, caused by distinct charged objects, are travelling through point P in the diagram. The resultant of these two electric fields is the net magnitude and direction of these electric fields at this position.

As a result, this location P has a unique electric field, indicating that no electric field lines cross there.

Furthermore, the electric lines that represent the field cannot cross at any given point in space. Of fact, that is not the situation here as the two lines come from two distinct places.

Two copper wires with different diameter are joined end to end. If a current flow in the wire combination, what happens to electrons when they move from the large diameter wire into the smaller diameter wire? Does their drift speed increase, decrease, or stay the same? If the drift speed change, what is the role the force that causes the change? Explain your reasoning.

A parallel-plate capacitor is connected to a power supply that maintains a fixed potential difference between the plates. (a) If a sheet of dielectric is then slid between the plates, what happens to (i) the electric field between the plates, (ii) the magnitude of charge on each plate, and (iii) the energy stored in the capacitor? (b) Now suppose that before the dielectric is inserted, the charged capacitor is disconnected from the power supply. In this case, what happens to (i) the electric field between the plates, (ii) the magnitude of charge on each plate, and (iii) the energy stored in the capacitor? Explain any differences between the two situations.

Q) A straight, nonconducting plastic wire 8.50 cm long carries a charge density of +175 nC/m distributed uniformly along its length. It is lying on a horizontal tabletop. (a) Find the magnitude and direction of the electric field this wire produces at a point 6.00 cm directly above its midpoint. (b) If the wire is now bent into a circle lying flat on the table, find the magnitude and direction of the electric field it produces at a point 6.00 cm directly above its center.

An emf source with E = 120 V, a resistor with R = 80.0 鈩�, and a capacitor with C = 4.00 碌F are connected in series. As the capacitor charges, when the current in the resistor is 0.900 A, what is the magnitude of the charge on each plate of the capacitor?

In the circuit shown in Fig. Q26.4, three identical light bulbs are connected to a flashlight battery. How do the brightnesses of the bulbs compare? Which light bulb has the greatest current passing through it? Which light bulb has the greatest potential difference between its terminals? What happens if bulb A is unscrewed? Bulb B? Bulb C? Explain your reasoning.
