22 and 23

**Question 22:** A very thick wire with radius 5.0 cm has a uniform current of 20 A flowing through the cross-section. Use Ampere’s Law to find the magnetic field 3.0 cm away from the center of the wire. Options: - a. 48 μT - b. 24 μT - c. 80 μT - d. 133 μT - e. none of these *Diagram Description:* The diagram shows a cylindrical wire with current \( I \) flowing through it. The arrow inside the wire indicates the direction of the current flow. The symbol \( R \) is noted near the wire’s edge, representing the radius. --- **Question 23:** For the RL circuit, find the time constant. Given: - \( R = 150 \) Ohms - \( L = 0.38 \) mH - \( E = 12.00 \) V Options: - a. 2.53 ms - b. 2.53 μs - c. 2.53 sec - d. none of these *Circuit Diagram Description:* The diagram shows an RL circuit with a switch. The switch has two positions \( a \) and \( b \). When in position \( a \), the circuit connects the voltage source \( E \) to the resistor \( R \) and inductor \( L \) in series.
