System is shown in the figure. Velocity of sphere A is 9 `(m)/(s)`. Find the speed of sphere B.

Text Solution

Verified by Experts

`|F|=v A sin theta` Here, `theta` is angle between `vec(v)` and `vec(A)` The particle moves undeflected if `vec(F)` acts be in positive z - direction. Hence, velocity should be in negative y - direction, or `vec(V)_(min)=-(mg)/(A)hat(j)`.
