Two identical small conducting spheres are separated by 0.60 m. the spheres carry different amounts of charge and each sphere experiences an attractive electric force of 10.8n. the total charge on the two spheres is -24 ? c. the two spheres are now connected by a slender conducting wire, which is then removed. the electric force on each sphere is closest to

Electrostatic force between two sphere is given by

here we know that

r = 0.60 m

F = 10.8 N

now we will have

since the two charges are attracting each other so here the two charges must be opposite in nature

now we will use

by solving above equation we will have

now the force between two sphere when connected by wire is to be determine

so here we have net charge on each sphere is half of total charge

so we will have

so force now is given as

this is repulsive force between two charges

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
