I I,- The picture shows two perpendicular wires where I1 is 14.6 amps, and I2 is 21.9 amps. The location A is in the plane of the two wires and is 25.0 mm from the x-axis and 15.9 mm from the y-axis.

1. A 0.190-A current is charging a capacitor that has circular plates 12.2 cm in radius. The plate separation is 4.00 mm. (a) What is the time rate of increase of electric field between the plates? (b) What is the magnetic field between the plates 5.00 cm from the center?
1. You've recently read about a chemical laser that generates a 20-cm-diameter, 25 MW laser beam. One day, after physics class, you start to wonder if you could use the radiation pressure from this laser beam to launch small payloads into orbit. To see if this might be feasible, you do a quick calculation of the acceleration of a 20-cm-diameter, 100 kg, perfectly absorbing block. What speed would such a block have if pushed horizontally 100 m along a frictionless track by such a laser?
