Question

$\left( 1 \right)$ State the law of magnetism.
$\left( 2 \right)$ State the law of charges.
$\left( 3 \right)$ What happens when a straw is rubbed with a sheet?

Answer 1

Hint: In this problem use the principle that like charges repel each other and unlike charges attract each other and use a friction created between them when we rubbed something so that this produced a separation of charges between them so use these characteristics to find the solution of the problem.

Complete step by step answer:
 The Magnetism Law
The most fundamental law of magnetism is that they repel one another like poles and attract one another unlike poles.
Charges law
Positively and negatively charged particles or atoms attract each other according to charging law, so electron and proton stick together according to this property as electron is charged negatively and proton is charged positively.
What happens when a straw is rubbed with a sheet?
As we know there is a tension created between them when we rubbed something so that this caused a division of charges between them makes one thing charged positively and another thing charged negatively so they stick together according to charges law.
So this is the required answer.

Note – In these questions also consider the property of the law of magnetism and the law of charges described above, and this definition is useful to find out what happens when a straw is rubbed with a board, because there is tension between them so that there is a division of charges between them so that one has been charged positively and another has been charged negatively in accordance with the above principle.
