In broad daylight, the size of your pupil is typically 3 mm. in dark situations, it expands to about 7 mm. how much more light can it gather?

31.4 mm²

Explanation:

Light gathering power of any telescope or eye can be defined by the formula,

Here, d is the diameter of the pupil.

Now for bright daylight the typical size or diameter of the pupil is 3 mm.

Now for dark situation the typical size or diameter of the pupil is 7 mm.

Increase in light gathering power.

Therefore the more light which can gather by eye is 31.4 mm² .

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
