1. The problem statement, all variables and given/known data
V=(KQ/L)((-ln(d))+(ln(L+d)))
is this correct? if not could some one tell me where i went wrong.
thanks in advance.
there is a part 2 to it as follows:
Imagine that distance d is much greater than the length of the rod. Intuitively, the potential should be approximately the same as the potential at a distance d from which of the following charge distributions?
a) an infinitely long wire with total charge Q
b) an infinitely long wire with total charge Qd/L
c) a point charge of magnitude Q
d) an electric dipole with moment QL
V=(KQ/L)((-ln(d))+(ln(L+d)))
not sure what the question trying to interpret, if i am correct as d>>L the charge becomes like a point charge
2. Relevant equations
V=(KQ/L)((-ln(d))+(ln(L+d)))
3. The attempt at a solution
so my claim is that as we go far we see it as a point charge. but i am not sure about this could someone explain this?
