You rub two 2.0-g balloons with a wool sweater. The balloons hang from 0.50-m-long very light strings. When you attach the strings together at the top, the balloons hang away from each other each string making an angle of 37∘ with the vertical.
Determine the magnitude of the electric force between the two charges?

Explanation:

given,

mass of balloons, m = 2 g

Length of the string, L = 0.5 m

angle made with vertical,θ = 37°

Magnitude of electric force, F = ?

Let F_e be the magnitude of the electric force between the balloons.

 T cos 37° = mg----------(1)

 T sin 37° = Fe------------(2)

dividing equation (2) by (1)

Magnitude of force between the two electric force is equal to

dang that balls went far

god i hope this !
