Hello!
what is the net force of this object if it is 400 N up and 600 N down?
In this case, as the meanings of the vectors are opposite, one of the forces receives the negative signal and thus a piece of the other vector is drawn, as shown in the figure. And to know the module of the resultant force, if it subtracts the modules of the forces.



Answer:
200N

The answer is: 42 .
Everybody knows that.
Answer:

Explanation:
Applying Gauss' Law to a cylindrical shell of radius 8 cm and height h, concentric to the charged shell, we get:

Where
is the charge per unit length, and so
is the charge inside the shell, and if we set
we can get the answer to our question.
Solving for
we get:

plugging in the values ( in SI units) we get:

Answer:
decrease
Explanation:
If the two charged ball attracts each other, it means the charge on both the balls are opposite in nature.
As, we insert a glass slab, it means a dielectric is inserted in between the charges. The force between them is reduced.
