Q. A thin 12 cm long solenoid has a total of 490 turns of wire and carries a current of 1.9 A. Calculate the magnitude of the field inside near the center.

Q. A helicopter flies over the arctic ice pack at a constant altitude, towing an airborne 118-kg laser sensor that measures the thickness of the ice. The helicopter and the sensor both move only in the horizontal direction and have a horizontal acceleration of magnitude 2.63 m/s2. Ignoring air resistance, find the tension in the cable towing the sensor.
