Your cousin has a birthday in the winter and while you are at their party, you start messing around with the balloons. You rub a red balloon on your sweater, you rub a blue balloon on the wall, and you rub a green balloon on your cousin's dog. All three balloons become charged. You notice that you can make the green balloon fall more slowly than normal (meaning it has an upward force) by holding the red balloon above it. Do the green and red balloons have the same charge or opposite charge? The green and red balloons have opposite charges ✓ ✓ You notice that you can make the green balloon fall more slowly than normal (meaning it has an upward force) by holding the blue balloon below it. Do the green and blue balloons have the same charge or opposite charge? The green and blue balloons have the same charge ✔✔ You now hold the red balloon above and the blue balloon below the green balloon at the same time. The green balloon now hovers, stationary, in the air. The red balloon has charge of 14 μC and is 1.0 m above the green balloon. What is the magnitude of the electric field at the position of the green balloon due to the red balloon ? Ered= The blue balloon has a charge of 20 μC and is 0.9 m below the green balloon. What is the magnitude of the electric field at the position of the green balloon due to the blue balloon? N Eblue= C What is the magnitude of the net electric field at the position of the green balloon due to the red and blue balloons? Enet = In order for the green balloon to hover, the Coulomb Force from the net electric field must exactly cancel its weight. The green balloon has mass of 0.0180 kg. What is the charge, in μC, on the green balloon? agreen= HC
