Lynn rubs a balloon with a piece of wool, which causes the balloon to pick up some of the electric charges from the wool. Lynn then observes that the balloon temporarily sticks to a wall. After several seconds, the balloon falls to the ground.
Which best describes the forces in this scenario?
The strong force causes the balloon to stick to the wall, and the weak force causes the balloon to fall to the ground.
The weak force causes the balloon to stick to the wall, and the strong force causes the balloon to fall to the ground.
The electromagnetic force causes the balloon to stick to the wall, and gravitational force causes the balloon to fall to the ground.
Gravitational force causes the balloon to stick to the wall, and electromagnetic force causes the balloon to fall to the ground.

The electromagnetic force causes the balloon to stick to the wall, and the gravitational force causes the balloon to fall to the ground.
Rubbing transfers charge to the balloon, which electrostatically attracts the (induced opposite) charges in the wall. As the charge leaks away or is neutralized, the electrostatic attraction weakens and gravity becomes dominant, so the balloon falls. The strong and weak nuclear forces are not relevant here.
