my teacher gave me this problem with a few different twists.
for example this one says the charge is diteibuted as p=Q/r and
then in my other problem he put p=Qr and another one he put
p=Q/r^2.
my question is can you please explain how this changes the
formula to solve this problem or better said can you please show it
step by step for the different variations so when i get something
on the exam i fully understand what...
