Q1. What current is required in the windings of a long solenoid that has 1710 turns uniformly dispersed over a length of 0.547 m in order to produce a magnetic field of magnitude 0.0002 T at the center of the solenoid? The permeability of free space is 4π × 10-7 T • m/A.
respond in units of mA
Q2. Two charged particles are projected into a magnetic field that is vertical to their initial velocities. If the charges are deflected in opposite directions, what does this tell you about them? Overlook the interaction between these two particles.)
Q3. A gardener feels it is taking him too long to water a garden with a 3/8 in diameter hose. by what factor will his time be cut if he uses a 5/8 in diameter hose? Assume nothing else has changed.
