Abeam 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

The direction should be in the positive x direction.

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)

The direction should be in the positive x direction.
