Question

1. a series circuit consists of a ci=0.460uFcapacitor, a c2=0.130 uF capacitor is connected to a power source. The charge on C1 is 23.3uC

a. Find the charge on C2

b. Find the potential difference on each capacitorc.

c. Find the potential at the power source

3. Draw a figure below that shows the electric field lines for two point charges separated by a small distance. One charge is q1=+3q and the other one id q2=-2q

Determine the ratio q1/q2

4. A charge of -4.0 is at the origin and a second charge of 13.0nC is at 6.00m east of the first charge. Find the magnitude and direction of the electric field 2m east from the first charge in between the two charges. Draw a figure showing the charges and the electric fields.

Explanation / Answer

1) things in series share charge so 23.3 uC

2) Q = CV

so V1 = Q/C1 = 23.3E-6/0.46E-6= 50.65 V

V2 = Q/C2 = 23.3E-6/0.13E-6=179.23 V

3) V = V1 = V2 = 50.65 + 179.23=229.88 V

4) q1/q2 =-3/2
