A ball is held at rest in position A by two light cords. The horizontal cord is now cut and the ball swings upto position B . What is the ratio of the tension in the cord OB and OA in position B to that in position A originally?

Options:

Answer:

Solution:

$T_{A} cos 3 0^{\circ} = mg, T_{B} = mg cos 3 0^{\circ}$

$\frac{T _{B}}{T _{A}} = cos^{2} 3 0^{\circ}$
