A) depends on v arid not on R
B) depends on R and not on v
C) is independent of both v and R
D) depends on both v and R
Correct Answer: C
Solution :
The time period of circular motion of the charged particle is given by \[=1\times 12=12\text{kg}\,\text{m}{{\text{s}}^{-1}}\]or\[=2\times 8=16\text{kg}\,\text{m}{{\text{s}}^{-1}}\] Hence, time period of rotation of the charged particle in uniform magnetic field is independent of both v and R.
