Two particles `A` and `B` of masses `m_A` and `m_B` respectively and having the same charge are moving ina plane. A uniform magnetic field exists perependicular to this plane. The speeds of the particles are `v_A` and `v_B` respectively and the trajectories are as shown in the figure. Then,

Options

A. `m_(A)v_(A)ltm_(B)v_(B)`
B. `m_(A)v_(A) gt m_(B)v_(B)`
C. `m_(A)ltm_(B)` and `v_(A)ltv_(B)`
D. `m_(A)=m_(B)` and `v_(A)=v_(B)`

Answer

B

Explanation

Radius of the circle `=(mv)/(Bq)` or radius `prop mv` if B and q are same `("Radius")_(A)gt("Radius")_(B):.m_(A)v_(A)gtm(B)v_B)`
