An electron initially traveling at a speed of 10^5 m/s enters a region where there is a uniform magnetic field of 2 T oriented 45 degrees to its initial velocity. Quantitatively describe the trajectory of the electron, including its path, the orbi
Find the magnitude and direction of the electric field that the 6.0 nC and the -3.0 nC charges together create at the origin. The 6.0 nC charge is at 0.300 m along the x-axis. The -3.00 nC charge is -0.100 m along the y-axis.
A certain disease is found in one person in 5000. If a person does have the disease, the test will show a positive result 93% of the time. If a person does not have the disease, the test in 1 out of 500 cases will give a false positive result. (hi
