Chapter 21: Q4P (page 625)

In the return stroke of a typical lightning bolt, a current of 2.5×104Aexists for20μs. How much charge is transferred in this event?

Short Answer

Expert verified

Answer:

  1. The charge transferred in this event is 0.50 C.

Step by step solution

01

The given data

  1. Current of the lightning bolt,I=2.5×104A
  2. Time of the current flow,t=20μs
02

Understanding the concept of current flow

The current of a conductor can be defined as the stream of charged particles within a conductor flowing for a given time. For a charge q passing through the cross-section of the conductor in time t, the current I is given as-

I=qt········································1

03

Calculation of the charge transferred in the event

The charge transferred by the lightning bolt can be calculated using the given data in equation (1) as follows:

q=I×t=2.5×104A20×10-6s=50×10-2As=0.50C

Hence, the value of the charge transferred in the event is 0.50 C .

In Fig. 21-27a, particle 1 (of charge q1) and particle 2 (of chargeq2) are fixed in place on an x-axis, 8.00cmapart. Particle 3 (of chargeq3=+8.00×10-19C) is to be placed on the line between particles 1 and 2 so that they produce a net electrostatic force on it. Figure 21-27bgives the xcomponent of that force versus the coordinate xat which particle 3 is placed. The scale of the x-axis is set by xs=8.0 cm. What are (a) the sign of charge q1 and (b) the ratio q2/q1?

In Fig. 21-39, two tiny conducting balls of identical mass mand identical charge hang from non-conducting threads of length L. Assume that u is so small that tan u can be replaced by its approximate equal, sin u.

(a) Show thatx=(q2L2πε0mg)1/3gives the equilibrium separation xof the balls.

(b) If L=120cm,and, x=5.0cmwhat is|q|?

Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of 0.108Nwhen their center-to-center separation is50.0cm. The spheres are then connected by a thin conducting wire. When the wire is removed, the spheres repel each other with an electrostatic force of 0.0360N. Of the initial charges on the spheres, with a positive net charge, what were (a) the negative charge on one of them and (b) the positive charge on the other?

A charge of 6.0 μCis to be split into two parts that are then separated by3.0mm.What is the maximum possible magnitude of the electrostatic force between those two parts?

In Fig. 21-26, particle 1 of charge +qand particle 2 of charge +4.00q are held at separation L=9.00cmon an x-axis. If particle 3 of charge q3 is to be located such that the three particles remain in place when released, what must be the (a) xand (b) ycoordinates of particle 3, and (c) the ratio q3/q?
