Balls Force

In summary, the electric force is equal to the horizontal component of the tension, the weight is equal to the vertical component of the tension, and T=\sqrt{(mg)^2+F_e^2}.

sqrt(4a^2sin^2(10)) = 2*a*sin10

How do you get from 1 - cos^2(10) - sin^2(10) to 2 sin^2(10) ?

1 - cos^2(10) + sin^2(10) = 2sin^10 because cos^2(10) + sin^2(10) = 1

FAQ: [Electrical force] 2 balls hanging from ceiling, angled

How does the electrical force affect two balls hanging from the ceiling at an angle?

The electrical force between two objects depends on their charges and the distance between them. If the balls have opposite charges, they will be attracted to each other and the angle between them will decrease. If the balls have the same charge, they will repel each other and the angle between them will increase.

Why do the balls hang at an angle instead of directly below each other?

The angle at which the balls hang is determined by the balance of forces acting on them. The weight of the balls pulling downwards is balanced by the tension in the string holding them up. The electrical force between the balls also plays a role in determining the angle at which they hang.

What factors affect the strength of the electrical force between the two balls?

The strength of the electrical force between the balls depends on the magnitude of their charges and the distance between them. The force is stronger if the charges are larger and closer together, and weaker if the charges are smaller and farther apart.

How does the angle between the balls change if one of the balls is given a different charge?

If one of the balls is given a different charge, the angle between them will change. If the balls have opposite charges, the angle will decrease as they are attracted to each other. If the balls have the same charge, the angle will increase as they repel each other.

Can the angle between the balls be used to determine the strength of the electrical force?

No, the angle between the balls alone cannot be used to determine the strength of the electrical force. Other factors, such as the charges of the balls and the distance between them, must also be taken into account to accurately calculate the strength of the force.
