If C = 16 p^F, determine the equivalent capacitrance for the combination shown.

Question

If C = 16 p^F, determine the equivalent capacitrance for the combination shown. 5) A 9-mu F capacitor and a 25- mu F capacitor are connected in series, and this combination is charged to a potential difference of 22 v. How much energy is then stored in this capacitor combination? 6) Two charges q^1 = +5 times 10^-9 C and q^2 = + 8 times 10^-9 C are placed 40.0 cm apart. A third particle of mass 30 mu g, and charge q^3 = 5 times 10-^9 C is places between the two particles such that it is 25 cm from q^1 as shown in the diagram belwo. Determine the accelereation of of the chage q^3 as a result of the net force applied by the two other charges 7) three charges q^1, q^2, and q^3 are arranged at the comers of a rectangle of side and H as shown in the diagram below. What is the electrostatic potential energy necessary to bring a test charge qo from infinty and place it at the open corner? The values or the charges and the sides and the sided of the rectangle are as indicated in the table below

Explanation / Answer

4.

combination of two parallel resistance is given as Cp

Cp = C + C = 2C

Cp , C and 2C are in series and their combination is given as

1/Cequivalent = 1/Cp + 1/C + 1/2C

1/Cequivalent = 1/2C + 1/C + + 1/2C

1/Cequivalent = 1/32 + 1/16 + + 1/32

Cequivalent = 8 pF
