Answer:

1. +3 charge is on the cylinder.

2. 0 charge is on the cuboid.

3. 0 charge is on the sphere.

4. +4 charge on the rectangle

5. -1 charge is on the atom.

6. +20 charge is on the atom.

7. +100 charge is on the object.

Explanation:

1. There are 5 positive charges and 2 negative charges in the cylinder. The 2 negative charges cancel out only 2 positive charges. 3 positive charges are left, making the cylinder positively charged.

(+5) + (-2) = +3

2. There are equal numbers of positive charges and negative charges. There are 8 positive charges and 8 negative charges. They all cancel out each other, making the cuboid neutral.

(+8) + (-8) = 0

3. There are equal numbers of positive charges and negative charges. There are 8 positive charges and 8 negative charges. They all cancel out each other, making the sphere neutral.

(+8) + (-8) = 0

4. There are 8 positive charges and 4 negative charges in the rectangle. The 4 negative charges cancel out only 4 positive charges, creating a positively charged rectangle.

(+8) + (-4) = +4

5. There are 16 electrons and 15 protons in the atom. The 15 protons cancel out only 15 electrons, making the atom negatively charged or anionic.

(+15) + (-16) = -1

6. There are 100 electrons and 120 protons in the atom, the 100 electrons cancel out only 100 protons. 20 protons are left, making the atom positively charged or cationic.

(+120) + (-100) = +20

7. The neutral object loses 100 electrons, now it has 100 extra protons. Hence, it is positively charged.

= +100
