The block is sitting at rest on the floor. the normal force on
is 3.00 n. find the mass of the block.

Mass=0.305[kg]

Explanation:

The block is located on a surface, where no forces act on it, so it will remain at rest according to Newton's laws.

We can perform an analysis of forces on the y-axis (see the free body diagram) and in order to determine the equation to determine the mass of the body, we must remember that the value of a force influenced by gravity is equal to the product of mass by acceleration.

From this equation we can clear the value of the mass

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
