Which net charge could be found on an object? -1.8 10-18 c -0.80 10-19 c +2.4 10-19 c +3.2 10-18 c

+3.2 10-18 C

Explanation:

The net electric charge on an object is determined by the number of protons or electrons on the object, therefore it must be an integer multiple of the proton/electron charge, whose value is

So, let's analyze each option provided:

-1.8 10-18 C --> not an integer multiple of the fundamental charge

-0.80 10-19 C --> not an integer multiple of the fundamental charge

+2.4 10-19 C --> not an integer multiple of the fundamental charge

+3.2 10-18 C --> this is an integer multiple of the fundamental charge: in fact, we have

So, the last option is the correct answer.

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
