You have a neutral balloon.
What is its charge after 12000 electrons
have been removed from it? The elemental
charge is 1.6 × 10−19 C.
Answer in units of µC.
To find the charge of the balloon after 12000 electrons have been removed, we need to calculate the total charge.
The elemental charge is given as 1.6 × 10^(-19) C, which represents the charge of a single electron.
To find the total charge, we can multiply the elemental charge by the number of electrons removed:
Total charge = Number of electrons × Elemental charge
Total charge = 12000 × (1.6 × 10^(-19) C)
Calculating this value, we get:
Total charge = 12000 × (1.6 × 10^(-19) C)
Total charge = 1.92 × 10^(-14) C
The charge is given in Coulombs (C), but we need to express it in units of microCoulombs (µC).
To convert Coulombs to microCoulombs, we divide by 10^(-6):
Charge in µC = Total charge / 10^(-6)
Charge in µC = (1.92 × 10^(-14) C) / 10^(-6)
Charge in µC = 19200 µC
Therefore, the charge of the balloon after 12000 electrons have been removed is 19200 µC.
To determine the charge of the neutral balloon after 12000 electrons have been removed, we need to first calculate the total charge of the removed electrons.
Given that the elemental charge is 1.6 × 10−19 C and we have removed 12000 electrons, we can calculate the total charge (Q) of the removed electrons as follows:
Q = (charge of one electron) × (number of electrons)
Q = (1.6 × 10−19 C) × (12000)
Q = 1.92 × 10−15 C
Now, let's convert the total charge to units of µC (microcoulombs).
Since 1 C = 10^6 µC, we can convert the total charge from coulombs to microcoulombs:
Q_micro = Q / 10^6
Q_micro = (1.92 × 10−15 C) / (10^6)
Q_micro = 1.92 × 10−21 µC
Therefore, the charge of the neutral balloon after 12000 electrons have been removed is 1.92 × 10−21 µC.
- (1.2*10^4 )(1.6*10^-19)
= 1.9 *10^-15 C
= 1.9 * 10^-9 µC
