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

A

Towards left

B

Towards right

C

Downwards

D

Upwards

Text Solution

Verified by Experts

The correct Answer is:
d
Refer the following figure to understand the arrangement:

Using the right hand palm rule, we can see that the direction of the magnetic field due to upward current on electrons is towards right. Direction of cross product of `vecv " and " vec B` is downwards, but the electron being a negatively charged particle will experience force opposite to it. Hence, the force experienced by electron beam will be upwards. Thus, option (d) is correct.
