The piece of plastic has 1.256× 10¹³ protons more than that of electrons.
What are protons and electrons?
A proton is a subatomic particle with a defined mass of 1 and a charge of +1 (positive charge). The symbol for the proton is either p or p+.
An electron is a subatomic particle that has a negative electric charge and that actively orbits the nucleus of the atom .
To calculate ,
given ,
magnitude of charge , q=+2μC=+2×10⁻⁶
Since, protons carry positive charge. Then, we know that standard number of proton in 1 Coulomb of charge is,
1C=6.28×10¹⁸ protons
Number of protons in 1 microcoulomb charge is,
=6.28×10¹⁸×10⁻⁶
=6.28×10¹²
Then for the net charge of q, the number of protons is given as,
np= q×6.28×10¹²
np= 2×6.28×10¹²
np=1.256×10¹³ protons
Thus, the piece of plastic has 1.256×10¹³ more protons than electrons.
