Question

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

Answer 1

q1 = q₂= -3

therefore each sphere has the same charge of -3 untis

Step-by-step explanation:

The metallic spheres have mobile charge, so when the two spheres come into contact the total charge

Q_total = q₁ + q₂

Q_total = -2 -4

Q_total = -6 units

it is distributed in between the two spheres evenly since the charges of the same sign repel each other.

When the spheres separate each one has

q₁ = -6/2

q1 = q₂= -3

therefore each sphere has the same charge of -3 untis
