Question

Metal sphere A has a charge of -2 units and an identical metal sphere, B, has a charge of -4 units. If the spheres are brought into contact with each other and then separated, the charge on sphere B will be... SHOW WORK

Answer 1

Charge on A = -2 units

Charge on B = -4 units

When connected together

Total charge = = -6 units

On separation charge is equally distributed as the two have same size

so charge on each one = -3 units
