A proton moving in the positive x direction with a speed of 8.9 105 m/s experiences zero magnetic force. When it moves in the positive y direction it experiences a force of 1.7 10-13 N that points in the positive z direction. Determine the magnitude and direction of the magnetic field.

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, (due +x direction)

When it moves in the positive y direction it experiences a force of, (due positive z direction)

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

For direction :

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

the force on the thing and the distance the force moves the thing

0.11 m/s and 0.28 m/s should be correct
