Answer:

Charge on the other particle is given as

q_2 = 1.74 \times 10^{-18} C

Explanation:

As we know that the force between two charges is given as

F = \frac{kq_1q_2}{r^2}

here we know that

F = 7 N

r = 0.31 \mu m

q_1 = 4.3 \times 10^{-5} C

now we have

7 = \frac{9 \times 10^9 (4.3 \times 10^{-5}q_2}{(0.31\times 10^{-6})^2}

now we have

q_2 = 1.74 \times 10^{-18} C

You find a micrometer (a tool used to
MakcuM [25]

Explanation:

A micrometer is a measuring device or an instrument which is used to measure very minute measurements very accurately and precisely. It is mathematical tool used to provide accurate measurement for any mechanical components.

Now, if the micrometer that I have found is badly bent, it would provide faulty or wrong measurements both in terms of  precision and accuracy when compared to a high quality meter stick.
