Answer:

-3

Explanation:

When they brought in contact net charge = - 4 + (-2) = - 6

And they are identical so charges on both the sphere becomes equal that is - 3

Answer:

The charge on sphere B is -3C.

Explanation:

Given:

q_{A}= -2C

q_{B}= -4C

Here,

The charge on sphere A is denoted by q_{A}.

The charge on sphere B is denoted by q_{B}.

The net charge is denoted by N.

The charge on Sphere B after separation is demoted by Q_{B}.

The charge on Sphere A after separation is demoted by Q_{A}.

Now,

The net charge on the spere A and B,

N=q_{A} +q_{B} \\N=(-2)+(-4)\\N =-6C

Then,

When they are brought in contact with each other and then separated,        

The charges are distributed equally in both spheres.

By the equation,

Q_{A} =Q_{B} =\frac{N}{2} \\Q_{A} =Q_{B} =\frac{-6}{2} \\Q_{A} =Q_{B} =-3C

So, the charge on sphere B is -3C.
