Answer:
[tex]B=4.5\times 10^{-4}\ T[/tex]
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)
[tex]B=\dfrac{410}{9.1\times 10^5}\ T[/tex]
[tex]B=4.5\times 10^{-4}\ T[/tex]
The direction should be in the positive x direction.
