Two volleyballs, each of mass 0.300 kg, are charged by an electrostatic generator. each is attached to an identical string and suspended from the same point, as shown in Fiq.2. They repel each other and hang with separation 50.0 cm. The length of the string from the point of support to the center of a ball is 250 cm. Determine the charge on each ball.

Fiqure 2

is trinagle with equal sides 2.5 m and base is 0.5m

I got 2.8592x10^-6 ???

Yes, I get 2.86 * 10^-6

To determine the charge on each ball, we can use Coulomb's Law, which states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

First, let's convert the given values to SI units:
- Mass of each volleyball: 0.300 kg
- Separation between the volleyballs: 50.0 cm = 0.5 m
- Length of the string from the point of support to the center of a ball: 250 cm = 2.5 m

The given figure is a triangle with equal sides of 2.5 m and a base of 0.5 m. Based on this information, it seems that you are describing an equilateral triangle.

Now, let's calculate the charge on each ball:

1. Calculate the force of the repulsion between the volleyballs using Coulomb's Law:
Assuming the force is tension in the string:
F = Tension

2. Calculate the tension in the string:
Tension = Mass x Acceleration (using Newton's second law)

3. Calculate the acceleration:
Acceleration = v^2 / r (where v is the velocity and r is the radius)

4. Calculate the velocity:
Velocity = 2πf (where f is the frequency)

5. Calculate the frequency:
Frequency = 1 / Period

6. Determine the period:
Period = 1 / 2.5 (since the triangle is equilateral and the sides are identical)

7. Calculate the acceleration, tension, and force to find the charge on each ball.

It seems like the length of the string and the dimensions of the triangle you provided are not directly relevant to determining the charges on the balls.

Please double-check the information given and provide any additional relevant values if available.
