...off topic, but what course are you taking?

(i want to make sure I'll never have to cross paths with this bullshit in my lifetime)

My answer is “I haven’t got a clue either” but...after a bit of digging I’d say I would try figuring it out via Coulomb’s constant. I don’t know for sure if the angles are a red herring but I am suspicious. This probably is no help but I thought I’d give it a stab.

Sorry, i don't notice that the problem don't include the mass. For calculate the mass, you must protect the force electric and gravitational. Like the system is in equilibrium, the forces are equal and you can calculate the mass.

pon2 l. temu#30899971There are 3 forces acting on the top charge. F_electric, F_gravitational, F_tension.Espi2 l. temu#30900000There are three forces, electricity, tension and gravitation.
I believe he's going to need some more trigonometry to determine the gravitational force, as the mass of the charge wasn't disclosed in the problem.

Omg, best joke ever. You made my day xD

There are three forces, electricity, tension and gravitation.
To solve this problem, you choose the coordinate system with x in the direction of Tension and then you must select the forces in the x direction. You just have to multiply by the cosine and the sine of the angles.

T = P * cos (24º) + Fe * cos (12º)
