Capacitor C₁ Is Connected Alone to a Battery and Charged

question 9

Multiple Choice

Capacitor C₁ is connected alone to a battery and charged until the magnitude of the charge on each plate is 4.0 * 10^-8 C.Then it is removed from the battery and connected to two other capacitors C₂ and C₃, as shown.The charge on the positive plate of C₁ is then 1.0 *10^-8 C.The charges on the positive plates of C₂ and C₃ are:

• A)q₂ = 3.0*10 ^-8 C and q₃ = 3.0 *10 ^{- 8} C
• B)q₂ = 2.0 *10 ^{- 8} C and q₃ = 2.0 *10 ^{- 8} C
• C)q₂ = 5.0 * 10^-8 C and q₃ = 1.0 * 10^-8 C
• D)q₂ = 3.0* 10^-8 C and q₃ = 1.0 * 10^-8 C
• E)q₂ = 1.0 *10^-8 C and q₃ = 3.0 *10^-8 C
