# P Two Metal Spheres of Capacitance C1 and C2 Carry Some Charges. They Are Put in Contact and Then Separated. the Final Charges Q1 and Q2 on Them Will Satisfy - Physics

ConceptCapacitors and Capacitance

#### Question

Two metal spheres of capacitance C1 and C2 carry some charges. They are put in contact and then separated. The final charges Q1 and Q2 on them will satisfy

• Q_1/Q_2< C_1/C_2

• Q_1/Q_2 = C_1/C_2

• Q_1/Q_2 > C_1/C_2

• Q_1/Q_2 = C_2/C_1

#### Solution

Q_1/Q_2 = C_1/C_2

When the spheres are connected, charges flow between them until they both acquire the same common potential V.
The final charges on the spheres are given by
Q1 = C​1V and Q2 = C2V

therefore Q_1/Q_2 = (C_1V)/(C_2V) = C_1/C_2

Is there an error in this question or solution?
