1. Three point charges are aligned along the x-axis, as shown below. Find the magnitude and d Coulomb force on the 6 uC charge. (k,-9 10 n of the 6.00 C 1.50 AC 2.00 pC 3.00cm2.00 cm 2. In the diagram to the right, C 1-4 ?F.Q Find the equivalent capacitance. Find the charge and the voltage for each individual capacitor. a. b. 36V Q1- Q2- 03- 04- 3. In the diagram to the right, battery voltage AV- 36V, R1-2 a. Find the equivalent resistance b. Find the total current. c. Find the current and voltage for each individual Rz RyExplanation / Answer
2)
here,
C3 and C4 are in series , their equivalent capacitance , C5 = C3 * C4 /( C3 + C4)
C5 = 22 * 8 /( 22 + 8) uF = 5.87 uF
a)
as C1 , C2 and C5 are in parallel, the equivalent cacpacitance, Ceq = C1 + C2 + C5
Ceq = 12.4 uF
b)
the potential difference across C1 , V1 = 36 V
the charge across C1 , Q1 = C1 * V1
Q1 = 144 uC
the potential difference across C2 , V2 = 36 V
the charge across C2 , Q2 = C2 * V2
Q2 = 90 uC
the charge across C3 and C4 , Q3 = Q4 = V * C5 = 211.3 uC
the potential difference across C3 , V3 = Q3/C3 = 9.6 V
the potential difference across C4 , V4 = Q4/C4 = 26.4 V
