A 6 C metal sphere is brought into contact with a 8C metal sphere and then the spheres are separated. Which statement is true?
A. Each sphere will have a charge of 0 C
B. Each sphere will have a charge of 6 C
C. Each sphere will have a charge of 7 C
D. Each sphere will have a charge of 8 C
E. Each sphere will have a charge of 14 C

Answer: C. 7

Explanation: When two conducting spheres with charge contact each other, their charges always reach equilibrium.

In other words, they end up with same charge, which can be found by taking the average.  

(6+8)/2

14/2

7

which is your final answer, which corresponds to C.



C. Each sphere will have a charge of 7 C is true when a 6 C metal sphere is brought into contact with a 8C metal sphere and then the spheres are separated.

When two spherical conductors come into contact, they share their charges until they reach the same potential. Since they are identical, this means they will share charge equally. In this case, we sum the charges of both spheres and then divide by 2:

Total Charge = 6 C + 8 C = 14 C

So, each sphere will have:

Final Charge on each sphere = Total Charge / 2 = 14 C / 2 = 7 C
