Chapter 4: Q98PP (page 720)

Consider a bee with the mean electric charge found in the experiment. This charge represents roughly how many missing electrons? (a) $1.9 \times 10^{8}$ ; (b) $3.0 \times 10^{8}$ ; (c) $1.9 \times 10^{18}$ ; (d) $3.0 \times 10^{18}$

Short Answer

Expert verified

Option (a) $1.9 \times 10^{8}$ numbers of electrons are missing.

Step by step solution

The relation between number of electrons and a charge.

Given,

The charge of a bee $q = + 30 p C = + 30 \times 10^{- 12} C$ .

Therefore, the relation between the number of electrons for a charge $q$ is given by:

$n_{e} = \frac{q}{e}$

Calculating the number of electrons

We know that the value of each electron $e = 1.60 \times 10^{- 19} C / e l e c t r o n s$ , now putting all the values in the above equation we get:

$n_{e} = \frac{q}{e} = \frac{30 \times 10^{- 12} C}{1.60 \times 10^{- 19} C / e l e c t r o n} = 1.9 \times 10^{8} e l e c t r o n s$

Therefore, the number of electrons is $1.9 \times 10^{8}$
