A positively charged particle is moving in the xy-plane in a region where there is a non-zero uniform electric magnetic field B in the +z –direction and a non-zero uniform electric field in the +y-direction. Which of the following is a posible trajectory for the particle?
(GR9677 #86)
v is in the xy-plane
E is in +y-direction
→ F is in +y-direction
→ particle will be deflected by E in +y-direction
B is in +z-direction
→ F,v, B orthogonal to each other
→ E and B orthogonal to each other
Particle moving in an orthogonal direction with B will exhibit cyclotron (helix shaped motion).
Answer: B
