Analyze the following setup: Two identical balloons are hung by threads. Both are rubbed with the same silk cloth. What will be the observation and the force involved?
A.They will move toward each other due to magnetic force.
B.They will move away from each other due to electrostatic repulsion.
C.They will stay still because gravity is stronger.
D.They will move toward each other due to electrostatic attraction.
