Physics · Electric Charges and Fields

In an isolated electrostatics setup, two initially neutral insulating bodies \( X \) and \( Y \) are rubbed together, resulting in the transfer of \( 3.125 \times 10^{13} \) electrons from \( X \) to \( Y \). Simultaneously, inside the same isolated system, a neutral particle decays into a proton, an electron, and a neutrino. The net final charge on body \( Y \) and the total net charge of the entire isolated system are, respectively:

1. A
   \( -5\,\mu\text{C} \) and \( 0\,\mu\text{C} \)
2. B
   \( +5\,\mu\text{C} \) and \( +5\,\mu\text{C} \)
3. C
   \( -5\,\mu\text{C} \) and \( -5\,\mu\text{C} \)
4. D
   \( 0\,\mu\text{C} \) and \( 0\,\mu\text{C} \)
