A group of electrons is treated as a point charge of -1.12 x 10-18 C. How many electrons make up this point charge? Remember that each electron has a charge of -1.602 x 10-19 C. o 2 o 4 4 07​

7

Explanation:

Given that the total charge is given by;

C =nq

Where;

n = number of charges

q = quantity of charge

Where the total amount of charge is  -1.12 x 10-18 C and the magnitude of each charge is  -1.602 x 10-19 C

Then the number of electrons is obtained from;

n =  -1.12 x 10-18 C/ -1.602 x 10-19 C

n = 7

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
