1) In the notes I stated that a moving charge will have an electric field. This electric field will produce a magnetic field that is out of phase with the electric field. Suppose, the magnetic field will have a field strength of 1.2 x 10 -3 T and the electric field will have a field strength of 4.6x 10 ³ N/C. If a positive charge with a value of 1.8 µC propagates perpendicular to both fields, at a speed of 3.1 x106 m/s
a) What is the size of the net force that the positive charge will feel?
How various g's of acceleration does the astronaut experience when the device is rotating at top speed? Each 9.80 m/s^2 of acceleration is 1 g.
100 g ball of clay is thrown horizontally with a speed of 13m/s toward a 900g block resting on a frictionless surface. It hits the block and sticks. The clay exerts a constant force on the block during the 7 ms it takes the clay to come to rest re..
