Homework Answers
a) correct
b) False
Gauss's law in electrostatic don't talk about magnetism it talks about electric flux passing through a closed surface
c) False
d) False , it is actually Faraday's Law
e)False
correct statement is that it is not possible to find the magnetic monopole in nature like
north and south pole can't exit alone
f) False
north-west
g) true
