Chapter 4: Q45E (page 716)

If two electrons are each from a proton (Fig. E21.45), find the magnitude and direction of the net electric force they will exert on the proton.

Short Answer

Expert verified

The magnitude of net electric force is and direction is

Step by step solution

01

About Net electric Force exert on proton

If a particular charge encounters two or more interactions, then the net electric force is the vector sum of those individual forces.

Direction is given by

02

Determine the magnitude and direction of the net electric force exert on the proton.

Distance between two electron

Solve for force exerted for each electron on proton

Solve for horizontal direction

solve for vertical direction

Solve for magnitude of net force

Solve for the direction of netelectricforce

Therefore the magnitude of net electric force is and direction is

03

Plot the Graph for showing the force

Suppose a resistor R lies alongeach edge of a cube (12 resistors in all)with connections at the corners. Find theequivalent resistance between two diagonally opposite corners of the cube (pointsa and b in Fig. P26.84).

The text states that good thermal conductors are also good electrical conductors. If so, why don’t the cords used to connect toasters, irons, and similar heat-producing appliances get hot by conduction of heat from the heating element?

A fuse is a device designed to break a circuit, usually by melting when the current exceeds a certain value. What characteristics should the material of the fuse have?

Copper has 8.5×1022free electrons per cubic meter. A 71.0-cm

length of 12-gauge copper wire that is 2.05 mm in diameter carries 4.85 A of

current. (a) How much time does it take for an electron to travel the length

of the wire? (b) Repeat part (a) for 6-gauge copper wire (diameter 4.12 mm)

of the same length that carries the same current. (c) Generally speaking,

how does changing the diameter of a wire that carries a given amount of

current affect the drift velocity of the electrons in the wire?
