Answer
The basketball on the right is in equilibrium.
Work Step by Step
The basketball on the left is not in equilibrium. The force directed down is greater in magnitude than the force directed up, therefore there is a net force on the ball which is pointing down.
The basketball on the right is in equilibrium. The horizontal force pointing to the right is equal in magnitude and opposite to the horizontal component of the force pointing at an angle. The vertical force pointing downward is equal in magnitude and opposite to the vertical component of the force pointing at an angle. Therefore, the net force on the basketball is zero.
