Two one-coulomb point charges are at a distance of 1.67 m from each other. What is the size of the electric force between the tw

pychu [463]

Explanation:

The given data is as follows.

distance (r) = 1.67 m

$q_{1} = q_{2}$ = 1 C

It is known that formula for electric force between two charges is as follows.

F = $\frac{kq_{1} \times q_{2}}{r^{2}}$

Hence, putting the given values into the above formula as follows.

$\frac{9 \times 10^{9} \times 1 \times 1}{(1.67)^{2}}$

= $3.227 \times 10^{9}$

As it is given that mass of Falcon Heavy rocket is 1421. Therefore, weight of 1 Falcon rocket is as follows.

weight of 1 falcon rocket = $142 \times 10^{3} \times 9.8$

Therefore, number of falcon rockets will be calculated as follows.

No. of falcon rockets = $\frac{3.227 \times 10^{9}}{142000 \times 9.8}$

= $2.31897 \times 10^{3}$

= 2318.9 falcons

Thus, we can conclude that force between the two point charges above is equal to the weight of 2318.9 Falcon Heavy rockets.

3. If an undetected air bubble was trapped inside the gas collection tube, how would this affect your calculated percent yield?

soldi70 [24.7K]

When an air bubble gets trapped inside the gas collection tube, then the gas that is actually collected becomes impure. This will definitely give an inaccurate result and the calculated percentage yield will be wrong. I hope that this is the answer that you were looking for and it has come to your help.
