Two small balls of mass m each are suspended side by side by two equal threds to length L. 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)^(2)g)`
C. `tan^(-1)"((a-X)^(2)g)/(mG)`
D. `tan^(-1)"((a^(2)-X^(2))g)/(mG)`

Answer

B
