Case Study: Read the following paragraph and answer the questions:
In a beam of charged particles, not all particles move with the same speed. A charged porticle with mass m, charge q and speed v 'enters a region of space where.-electric field and magnetic fields are perpendicular to particle's velocity and to each other. Magnetic force is upward with magnitude qVB. When the total force is zero, there is no deflection om `(v) = (E) /( B) `

A charged particle enters `vecE = 50 NC^(-1)` and `vecB = 2.5 xx 10^(-5)` weber `m^(-1)` . It comes out without any change with velocity of.

A

`10^(6) (m)/(s)`

B

`2.5 xx 10^(6) (m)/(s)`

C

`0.5 xx 10^(6) (m)/(s)`

D

`2xx 10^(6) (m)/(s)`

Text Solution

Verified by Experts

The correct Answer is:
D
`qE = qvB `
`implies v = (E )/(B )`
