A vertical wire carries a current in upward direction. An electron beam sent horizontally towards the wire will be deflected

A

towards right

B

towards left

C

upwards

D

downwards

Text Solution

Verified by Experts

The correct Answer is:
C
Lorentz force
`F _(m) =- e ( vecv xx vecB)`
`=-e ( - v_(0) veci xx B _(0) vecJ)`
`F_(m)= e v _(0) B _(0) hatB`
Since the force is in z direction
Therefore, the displacement of incoming beam of `e^(-)` will be in upward direction.

Two infinetely long, parallel wires are lying on the ground at distance a=1cm apart as shown in Fig. A third wire, of length L=10m and mass 400g, carries a current of I_1=100A and is levitated above the first two wires, at a horizontal position midway between them.
