Answer:

The magnitude of magnetic field is 1.19 T and its direction magnetic is in negative x direction.

Explanation:

Given that,

Speed of a proton, v=8.9\times 10^5\ m/s (due +x direction)

When it moves in the positive y direction it experiences a force of, F=1.7\times 10^{-13}\ N (due positive z direction)

We need to find the magnitude and direction of the magnetic field. The magnetic force is given by :

F=q(v\times B)\\\\B=\dfrac{F}{qv}\\\\B=\dfrac{1.7\times 10^{-13}}{1.6\times 10^{-19}\times 8.9\times 10^5}\\\\B=1.19\ T

For direction :

F=q(v\times B)\\\\k=(+q)(j\times B)\\\\B=-i

So, the magnitude of magnetic field is 1.19 T and its direction magnetic is in negative x direction.
