Calculate the Charge of Two Spheres Hung by a Thread | Coulomb's Law

Follow us:

Q. Two identical small spheres of mass 2.0 g are fastened to the ends of an insulating thread of length 0.60 m. The spheres are suspended by a hook in the ceiling from the centre of the thread. The spheres are given identical electric charges and hang in static equilibrium, with an angle of 30.0° between the string halves, as shown. Calculate the magnitude of the charge on each sphere.

When calculating the distance between. the two charges, you used 0.155 as your value for r, But would that only be half the distance between the two charges? aren't you supposed to use the whole distance between the two to find the value of magnitude charges?

I have a question about the beginning of this solution q1 and q2 are equal to each other, so wouldn't it be q^2, not just q??

I have a question. How to know the distance between that two identical spheres?

In GSS school in iraq we study the equilibrium just with 14 years old 🥲🇮🇶. It's so hard .
