Class 12 Gauss's Theorem Notes 
 
Gauss's Theorem (also known as Gauss's Law 
 
Gauss's theorem is a fundamental principle in electromagnetism that relates the flux of an electric field through a closed surface to the total charge enclosed by that surface. It's a powerful tool for simplifying calculations involving electric field. 
​ 
The right-hand side of the equation represents the total charge enclosed by the surface divided by the permittivity of free space. This ratio is a constant ...

PROBLEM 1 
A metal ball is buried in an ice cube that is in a bucket of water. 
(a) If the ice cube with the metal ball is initially under water, what happens to the water level 
when the ice melts? 
(b) If the ice cube with the metal ball is initially floating in the water, what happens to the water 
level when the ice melts? 
(c) Explain how the Earth’s average sea level could have increased by at least 100 m compared 
to about 20,000 years ago.

However, if the answer is incorrect, mark(s) can usually be gained by correct substitution / working and this is shown in the ‘extra information’ column or by each stage of a longer calculation. 
A calculation must be followed through to answer in decimal form. An answer in surd form is never acceptable for the final (evaluation) mark in a calculation and will therefore generally be denied one mark.
