Question

A beam of protons is directed in a straight line along the positive z ‑direction through a region of space in which there are crossed electric and magnetic fields. If the electric field magnitude is ????=410 V/m in the negative y ‑direction and the protons move at a constant speed of ????=9.1×105 m/s, what must the direction and magnitude of the magnetic field be in order for the beam of protons to continue undeflected along its straight-line tra

Answer 1

Answer: Um sorry i cant help i aint in physics:(

Answer 2

`B=4.5* 10^(-4)\ T`

The direction should be in the positive x direction.

Step-by-step explanation:

Given that

Electric filed E= 410 V/m (In Negative y direction)

V= 9.1 x 10 ⁵ m/s

As we know that

F= E q + q.V x B

Given that protons is moving constant speed so ,F=0

F= E q +q. V x B

0= E + V x B

E = -V x B

- 410 j = - ( 9.1 x 10 ⁵ k x B i)

`B=(410)/(9.1* 10^5)\ T`

`B=4.5* 10^(-4)\ T`

The direction should be in the positive x direction.
