Q1. An airplane pilot experiences weightlessness as she passes over the top of a loop-the-loop maneuver. If her speed is 210 m/s at the time, find out the radius of the loop. Draw all the forces on the pilot.

Q2. Two long, parallel conductors carry currents I1 = 3.10 A and I2 = 5.10 A, both directed into the plane of the computer screen. Find out the magnitude and direction of the resultant magnetic field at a point midway between the wires. (b) Find out the magnitude and direction of magnetic field at point P, located 20.0 cm above the wire carrying the 5.00-A current.
