Two small positively charged spherical balls are suspended from a common point at the ceiling by non-conducting massless strings of equal length $$\ell$$. The first ball has mass $$m_1$$ and charge $$q_1$$ while the second ball has mass $$m_2$$ and charge $$q_2$$. If the two strings subtend angles $$\theta_1$$ and $$\theta_2$$ with the vertical as shown, then

A

$$\frac{\sin\theta_1}{\sin\theta_2}=\frac{q_2}{q_1}$$

B

$$\frac{\sin\theta_1}{\sin\theta_2}=\frac{m_2}{m_1}$$

C

$$\frac{\tan\theta_1}{\tan\theta_2}=\frac{q_1}{q_2}\frac{m_2}{m_1}$$

D

$$\frac{\sin\theta_1}{\sin\theta_2}=1$$
