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 a charge of 8 μC and is 0.9 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 25 μC and is 1.2 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? Eblue= N C What is the magnitude of the net electric field at the position of the green balloon due to the red and blue balloons?
