Two particle A and B of masses mA and mB respectively and having the same charge are moving in a plane. A uniform magnetic field exists perpendicular to this plane. The speeds of the particles are vA and vB respectively and the trajectories are as shown in the figure. Then-
A
mAvA< mBvB
B
mAvA> mBvB
C
mA< mB and vA< vB
D
mA = mB and vA = vB
Answer
mAvA> mBvB
Explanation
Solution
use r =
