You're a little late. But if you want some short, quick rules, then these are
a couple that I would take in with me (stored only in my brain, of course):

-- If something is not accelerating or moving at all, then all the forces on it
must add up to zero. That could even mean a hanging rope.

-- In a vertical rope, the tension in it is the same everywhere in the rope.
The tension is the weight of whatever is hanging from the bottom.

That's really all I'm sure of, based on your hazy, fuzzy description of
what you've been doing in class. I don't want to get into things that
you might not have learned yet, and confuse you.

A researcher is analyzing data from a high-energy particle collision. the result of the analysis gives a value of 8.8 x 10-19 c

Harrizon [31]

Elementary charge used to determine charges of other objects is equal to a charge of electron or proton. It's value is roughly $1.6* 10^{-19} C$ . All other charges are whole-number multipliers of this elementary charge, meaning that we multiply elementary charge by {...,-2,-1,0,1,2,...}.

To find out if the measured charge can be accepted we need to divide it with elementary charge to see if we get whole number as result.
There are three possible values of measured charge: $8.7* 10^{-19} C\\ 8.8* 10^{-19} C \\ 8.9* 10^{-19} C$

$N_{1} = \frac{8.7* 10^{-19} C }{1.6* 10^{-19} C } =5.44 \\ N_{2} = \frac{8.8* 10^{-19} C }{1.6* 10^{-19} C } =5.5 \\ N_{3} = \frac{8.9* 10^{-19} C }{1.6* 10^{-19} C } =5.56$

As we can see none of the possible values of a measured charge is whole-number multiplier of elementary charge so the researcher should not accept the value.
This charge can be achieved by using quarks which have value of 1/3 of elementary charge but they do not remain stable for long enough.
