Question

Two identical metallic spheres A and B or exactly
equal masses m and m are taken. A has a+ve charge
of q coulomb and B has an equal negative charge.
If m and m, are the masses of A and B after
charging then

a) m = m;
b)mB.> mA

c)mp < mA
d)None of the above​

Answer 1

Answer:

The metallic ball which is given a charge of +Q Coloumbs, is actually electrons of charge −Q Coloumbs being taken out from it. This resulted in a decrease of mass of the sphere. The total mass of the sphere is reduced by the mass of all electrons being taken out.

The sphere which is given a charge of −Q Coloumbs, electrons of total charge −Q Coloumbs is injected into the sphere, thus increasing its mass by the mass of the total number of electrons injected inside it. Thus their masses after charging are different.
