A parallel-plate capacitor is formed from two 6.0-cm-diameter electrodes spaced 2.0mmapart. The electric field strength inside the capacitor is 1.0×106N/C. What is the charge (in nC ) on each electrode?

Short Answer

Expert verified

One electrode has 25nCcharge and other one has -25nCcharge.

Step by step solution

01

Introduction

Electric field Einside circuit is: 1×106N/C. The plate of a circuit has a diameter of6cmand they are 20cmdistance apart.

Formula used

Due to the area capacitor, there is an electric field. Aand charge Q

E=QϵoA...........(1)(1)

02

Explanation

Radius of disk is

r=6cm2

=3cm

Now sum charge from equation (1)

Q=EϵoA

=1×106N/C8.85×10-12C2/N·m2π(0.03m)2

=25nC

03

Find the charge on one electrode

The charge on one electrode is 25nC, whereas the other is -25nC.

A parallel-plate capacitor has 2.0cm×2.0cmelectrodes with surface charge densities ±1.0×106C/m2. A proton traveling parallel to the electrodes at 1.0×106m/s enters the center of the gap between them. By what distance has the proton been deflected sideways when it reaches the far edge of the capacitor? Assume the field is uniform inside the capacitor and zero outside the capacitor.

An infinite plane of charge with surface charge density 3.2μC/m2has a 20-cm-diameter circular hole cut out of it. What is the electric field strength directly over the center of the hole at a distance of 12cm?

Hint: Can you create this charge distribution as a superposition of charge distributions for which you know the electric field?

One type of ink-jet printer, called an electrostatic ink-jet printer, forms the letters by using deflecting electrodes to steer charged ink drops up and down vertically as the ink jet sweeps horizontally across the page. The ink jet forms30μm diameter drops of ink, charges them by spraying 800,000 electrons on the surface, and shoots them toward the page at a speed of 20m/s. Along the way, the drops pass through two horizontal, parallel electrodes that are 6.0mmlong,4.0mm wide, and spaced 1.0mm apart. The distance from the center of the electrodes to the paper is 2.0cm. To form the tallest letters, which have a height of 6.0mm, the drops need to be deflected upward (or downward) by 3.0mm. What electric field strength is needed between the electrodes to achieve this deflection? Ink, which consists of dye particles suspended in alcohol, has a density of 800kg/m3 .

You've hung two very large sheets of plastic facing each other with distancedbetween them, as shown inFIGUREEX23.20. By rubbing them with wool and silk, you've managed to give one sheet a uniform surface charge density and the other a uniη1=-η0form surface charge density η2=+3η0. What are the electric field vectors at points1,2and3?
