For the conditions given in the previous question, the charge’s actual trajectory is:
A. a circle bending to the left
B. a parabola bending to the left
C. a circle bending to the right
D. a parabola bending to the right
Answer:
Let v = v j
B = -Bo k
q = -qo
Force F = q v x B = -qo (-vBo i) = qo*v*Bo i.
Hence directed towards the positive axis
perpendicular to the direction of motion
Hence a circle bending towards right.
