my question is as follows:
when do we need to consider a three dimension body as a point like body in our calclulations?
i mean outside our theoretical/homework practices when should we assume the body as a point like?
one thing i can think of is when the geometric properties of a body is not important and therefore isn't taken into consideration into our calculations.
and maybe also when the body is a particle but other than that i don't know.
