Chapter 4: Q21E (page 810)

For the system of capacitors shown in Fig. E24.21, a potential difference of 25 V is maintained across ab.

(a) What is the equivalent capacitance of this system between a and b?

(b) How much charge is stored by this system?

(c) How much charge does the 6.5-nF capacitor store?

(d) What is the potential difference across the 7.5-nF capacitor?

Short Answer

Expert verified

The equivalent capacitance for the system is 19.29nF

The net charge stored in the system is 482.35nC

The charge is stored across the 6.5nF register is 162.5nC

The potential difference across terminals (a,b) is 25Vb

Step by step solution

01

Step 1:

Given capacitors as shown in the figure.

The equivalent equation for the three capacitors in the middle

To get the equivalent capacitance for the system we add the three capacitance

02

Step 2:

b) The net charge is

03

Step 3:

C) The charge is stored across the 6.5nF register.

04

Step 4:

The potential difference across terminals (a,b) is same as they are connected in parallel.

(c) A battery with emf and internal resistance 0.50惟is inserted in the circuit at d, with its negative terminal connected to the negative terminal of the 8.00-Vbattery. What is the difference of potential Vbcbetween the terminals of the 4.00-Vbattery now?

An alpha particle (a He nucleus containing two protons and two neutrons and having a mass of 6.64脳10-7kg) travelling horizontally at 35.6km/senter a uniform, vertical,1.80-T magnetic field.(a) What is the diameter of the path followed by this alpha particle? (b) what effect does the magnetic field have on the speed of the particle? (c) What are the magnitude and direction of the acceleration of the alpha particle while it is in the magnetic field? (d) explain why the speed of the particle does not change even though an unbalanced external force acts on it.

We have seen that a coulomb is an enormous amount of charge; it is virtually impossible to place a charge of 1 C on an object. Yet, a current of 10A,10C/sis quite reasonable. Explain this apparent discrepancy.
