C) The proton begins to move parabolically D) The proton both speeds up and moves parabolically E) The proton both slows down and moves parabolically.
Homework Answers
1) force on the proton will be along the direction of field as it has positive charge
option b is correct
2) electron has negative charge therefore force on it will act in the opposite direction of field
option a is correct
3) velocity of proton along x axis will be constant and velocity of it along y axis will increase from zero, therefore motion of the proton will be like projectile.
Option c is correct
