You hold a ruler that has a charge on its tip 2 cm above a small piece of tissue paper to see if it can be picked up. the ruler has −14 µc of charge. the tissue has 3 g of mass. what is the minimum charge required to pick up the tissue paper?

Explanation:

It is known that the relation between force and mass is as follows.

                            F = mg .......... (1)

where,    F = force

              m = mass

              g = acceleration due to gravity

Also,     F = .......... (2)  

Therefore, equating equations (1) and (2) as follows.

                = mg

Putting the given values into the above formula as follows.

              = mg

            = 3 g \times 9.8[/tex]

              C

Therefore, the minimum charge required to pick up the tissue paper is C.

the body's situation won't change the forces are equal opposit and on the same body

neither accurate nor precise.
