Two small balls of mass m each are suspended side by side by two equal threads of length L as shown in the figure. If the distance between the upper ends of the threads be a, the angle `theta` that the threads will make with the vertical due to attraction between the balls is

Options

A. `tan^-1((a-X)g)/(mG)`
B. `tan^-1(mG)/((a-X)^2g)`
C. `tan^-1((a-X)^2g)/(mG)`]
D. `tan^-1((a^2-X^2)g)/(mG)`

Answer

B
