An electron is injected with a velocity u0=ayu0 into the y>0 region where both an electric field E and a magnetic fieldB exist. Describe the motion of the electron if
A) E = azE0 and B = axB0
B) E = -azE0 and B = -azB0
Discuss the effect of the relative magnitudes of E0 and B0 on the electron paths in parts (A) and (B).
the second half of the swim, and (c) the round trip. (Assume that time t2 is from the other end of the pool to the starting point. Use any variable or symbol stated above as necessary. Indicate the direction with the sign of your answer.)
