Question

two similar charged small spheres each having a charge of 0.044 micro coulombs are suspended from a point by a thread of length 15 cm each. at equilibrium the angle is 5 degree. what is the mass of each sphere ?
Tsin(α/2)=kq²/{2Lsin(α/2)}²,
Tcos(α/2)=mg.

tan(α/2)= kq²/mg{2Lsin(α/2)}²,
m= kq²/g{2Lsin(α/2)}²•tan(α/2)=...
