Musiyano unogona kuitika

Mibvunzo mitatu nezve Potential difference equation

1. Chaja yemagetsi inofambiswa mumunda wemagetsi wakafanana une simba re2√3 N chinhambwe che20 cm. Kana divi resimba riri pakona ye30 ^o kusvika pakubviswa kwechaja yemagetsi, musiyano uripi pakati pesimba remagetsi panzvimbo dzekutanga nedzekupedzisira dzechaja yemagetsi.

Anozivikanwa:

Simba (F) = 2√3 N

Nhambwe (s) = 20 cm = 0.2 m

Angle (θ) = 30 ^o

Zvinodiwa: Musiyano wemagetsi

Solution:

Basa rekutumira chaji +q kubva kuna a kuenda kuna b rakaenzana nemusiyano wesimba remagetsi papoindi a na b.

ΔEP = ΔW

Kana divi resimba F maererano nedivi rekutumira chaji +q rakatenderedzwa ne θ, saka basa rekutumira chaji +q kubva kuna a kuenda kuna b nderekuti:

ΔW = F Δs cos θ = (2√3)(0,2)(cos 30) = (0,4√3)(0,5√3) = (0,2)(3) = 0,6 Joules

2. Kana chaji uye kugona kwema capacitor zvichizivikanwa kuti 5 µC uye 20 µF, zvichiteerana, sarudza musiyano unogona kuitika wema capacitor.

Anozivikanwa:

Chaja yemagetsi (q) = 5 µC = 5 x 10^-6 C

Kugona kwe capacitor (C) = 20 µF = 20 x 10^-6 F

Kuda: Musiyano we capacitor potential (V)

Solution:

Fomura yekusiyana kwe capacitor potential, capacitor capacitor uye chaji:

V = q / C = (5 x 10)^-6) / 20 x 10^-6 = 5/20 = 0,25 Volts

3. Mapoinzi maviri emagetsi QA = -4 µC uye QB = 8 µC ari kure ne16 cm. Sarudza simba remagetsi pakati pemapoinzi maviri aya.

Anozivikanwa:

Chaja yemagetsi 1 (Q)_A) = 4 x 10^-6 C

Chaja yemagetsi 2 (Q)_B) = 8 x 10^-6 C

Kureba (r) = 8 cm = 0,08 m

Chikamu cheCoulomb (k) = 9 × 10⁹ Nm²/C²

Kuda: Simba remagetsi paC (V)_C)

Solution:

V_A = k Q / r = (9 × 10)⁹)(4 x 10^-6) / 0,08 = (36 × 10³) / 0,08 = -450 Volts

V_B = k Q / r = (9 × 10)⁹)(8 x 10^-6) / 0,08 = (72 × 10³) / 0,08 = 900 Volts

Simba remagetsi paC (V)_C) = 900 – 450 = 450 Volt
