**★C****ase 1:**

If the conductors having same radius then :-

Do algebraic sum of charges on both conductors and divide it by two and you will get the answer.

After conduction charge on both conductors will be =

(charge on 1st + charge on 2nd)/2

**Let’s learn with some examples:**

Charge on first conductor= +5C

Charge on 2nd conductor = -13C

So after conduction Final charge on both

5 + (-13) /2 = -4 C

So the Final answer is -4 C

**★Case 2:**

If radius of both the conductors are different.

Let you have two conductors having radius R1 and R2 respectively .

Then you need to use this formula to get the final charge on both the conductors

After conduction,

Charge on 1st conductor=

R1 / (R1 + R2) X (total charge)

Charge on 2nd conductor=

R2 / (R1 + R2) X (total charge)

**Let’s learn with some examples:**__Ex.__ Let you have to conducting sphere of radius 1cm and 2 cm having charge -3C and +5 C respectively. After conduction charge on (1) will be 1/3 X 2 = 2/3 C & (2) will be 2/3 X 2 = 4/3 C

It will not take more than 5 to 10 seconds to get the answer.
