Find force on electron if magnitude is 40
On a 200 km bike cycle ride, you ride the first 90 km at an average speed of 20 m/s. What must your average speed over the next 40 km be to have your average speed for the total 200 km be?
(a) 60 m/s?
(b) Given this average speed for the first 90 km, can you possibly attain an average speed of
80 m/s for the total 200 km ride? Explain.
Please reply as fast as possible
An electron in a uniform electric and magnetic field has a velocity of 1.20 104 m/s (in the positive x direction) and an acceleration of 2.00 1012 m/s2 (in the positive z direction). If the electric field has a magnitude of 20.0 N/C (in the positive z direction), what can you determine about the magnetic field in the region? What can you not determine
