There is the problem which i haven't been able to understand:
"Show that the tangential component of an electric field is continuous from one side of a conductor to the other"
What exactly is asked and how to prove it?
Thanks!
Hey,
The question is:
"AN object weighs 6.4 N when fully immersed in water. Find the buoyant force acting on it."
I have not even come near to the solution because it doesn't fit in the formula.
thanks in advance.
