Exit Check 6.2 - What is Charge

6.2.1

What is the total positive charge? Total negative charge? Net charge?

• +2, -4, Net charge = -1

• +1, -3, Net charge = -2

• +3, -5, Net charge = -2

• +5, -3, Net charge = +2

Answer explanation

This question links to success criteria 6.2.1: I can determine the net charge that an object has.

If you got it correct place a check mark in the question results section. If you got it incorrect place an X in that section. If this was a redemption question, cross out the one X and replace it with a check mark.

Two balloons are tied to the ceiling with equal length ropes. Balloon 1 has a charge of -14. Balloon 2 has a charge of -16. When let go, how will they move and why?

• Both balloons have negative charges. Since the charges are like charges, they attract

• One balloons negative charge is larger than the other. Because the charges are not the same size, nothing will happen.

• On balloon's negative charges are on the left side, the other's are on the right side. This will make the balloons spin in place.

• Both balloons have negative charges. Since the charges are like charges, they repel.

Based on the picture what is true about the charges

• Because the Styrofoam is stuck the cat it can no longer charge.

• The cat is going to charge the person because it is angry

• The cat and the Styrofoam must have different charges because the foam is attracted to the cat.

• The cat and the Styrofoam must have the same charges because the foam is attracted to the cat.
