**Scenario:**A non-conducting, non-magnetic cylindrical object of mass \( m \) and carrying a static charge of \( Q \) is placed inside a long solenoid that is carrying a constant current \( I \).Both the solenoid and the cylindrical object are motionless to begin with. Then, the current in the solenoid is reduced to \( I/2 \). The time it takes for the current to make this change is \( t \) seconds, and the cylindrical object begins to rotate, achieving a final angular speed of \( \omega \). Some time later, the current is restored back to \( I \). As before, the change from \( I/2 \) back to \( I \) also takes \( t \) seconds. What happens to the cylindrical object during the time that the current is being restored back to its original value?**Options:**- ∘ Its rotation speeds up until the angular speed reaches \( 2\omega \)- ∘ The rotation of the cylindrical object maintains the same magnitude but reverses direction- ∘ Its rotation slows and comes to a stop when the current gets back to its original value- ∘ It continues to rotate in the same direction at an angular speed of \( \omega \)

Required : The final speed of the charged non conducting cylinder placed inside the solenoid.

PLEASE ANSWER BOTH 1. It is desired to construct a solenoid that will have a resistance of 4.80 Ω (at 20°C) and produce a magnetic field of 4.00 ✕ 10−2 T at its center when it carries a current of 4.35 A.
