Question

Charge of 4.8 * 10-15 C is transformed from the plastic ruler to silk. How many electrons are
transformed in this process?​

Answer 1

$\maltese \: \red{\mid{\underline{\overline{\textbf{Answer}}}\mid}}$

There is an relation between charge number of electrons and charge of a electron. This relation says that total charge of a body is equals to the product of number of electrons in it and the charge of each electron. This is represented by the equation :

$\maltese \: \orange{\mid{\underline{\overline{\textbf{q = ne}}}\mid}}$

In this equation :

• Q = Total charge.
• n = number of electrons
• e = Charge of a electron.

For this case :

• Q = 4.8 × 10^-15C
• n = ?
• e = 1.6 × 10^-19C

Now by this equation we can say.

$\maltese \: n = \frac{q}{e}$

After inputting the known values here we get :

$n = \frac{4.8 \times {10}^{ - 15} }{1.6 \times {10}^{ - 19} }$

$n = 3 \times {10}^{4}$

Therefore 3×10^4 electrons was transferred in this process.
