- Homework Statement
- A proton is flying to the east near the surface of the earth at 1000m/s. What is the magnitude of the force (in N) the proton feels due to the earth's magnetic field?
- Relevant Equations
- F = qvBsin##\theta##
Plug in the elementary charge for q, 1000 m/s for v, 50 microtesla for B and 90 degrees for theta and I get about 8e-21 Netwons. But apparently this is wrong, anyone know why? Thank you.
