Answer:
Explanation:
The angle between the polariser 1 and 2 is 60°
If I₁ be the intensity of light after polariser 1 , its intensity after polariser 2 that is I₂ can be expressed as follows
I₂ = I₁ cos² 60
= I₁ x 1/4
= I₁ x 
When an atom becomes electrically charged the number of electrons or protons stops and they are not equal again. The "extra" electron or proton is not balanced by something inside the atom any longer and it starts attracting itself to othet protons or electrons in other atoms.
<h3>What is atomic structure?</h3>
An atomic structure comprises of positively charged nucleus which is surrounded by negatively charged particles called electron and neutron which is neutral charged.
Unlike charges attract each other while like charges repel each other.
Therefore, When an electron is fully charged, the number of electrons will stop to be unequal again.
