Solution

The correct option is A $$1$$
As the system is in equilibrium the construct force at $$A$$ is equal to the sin of contact force between $$A$$ and $$B.$$
Same for ball $$B.$$
The contact force at $$B$$ is same as the sin of contact force between $$A$$ and $$B$$ therefore the ratio is $$1:1$$
hence,
option $$(A)$$ is correct answer.
