Question

Two particles `A and B` of masses ` m_(A) and m_(B)` respectively and having the same charge are moving in a plane . The speeds of the particles are ` v_(A) and v_(B)` respectively and the trajectories are as shown in the figure. Then

A. `m_(A)V_(A) ltm_(B)V_(B)`
B. `m_(A)V_(A) gt m_(B)V_(B)`
C. `m_(A) lt m_(B) ` and `V_(A) lt V_(B)`
D. `m_(A) = m_(B) ` and `V_(A) = V_(B)`

Answer 1

Correct Answer - `B`
`r = (mv)/(qB)` Givent that `r_(A) gt r_(B)`
`m_(A) V_(A) gtm_(V) V_(B)` .
