Question

Under the influence of uniform magnetic field a charged particle moves with constant speed V in a circle of radius R the time period of rotation of particle

• A. Depend on R and not on v
• B. Is independent of both v and R
• C. Depends on both V and R
• D. Depends on V and not on R

Answer 1

The correct option is B Is independent of both v and R

Given: moving charge particle in uniform magnetic field

Solution: As we know the formula of time period of rotation in uniform magnetic field is $T=\frac{2\pi m}{qB}$

So, T is independent of both v &R

Hence the correct option is B
