Question

A positive charge is moving across a room from south to north. A magnetic field runs from east to west. In what direction is the magnetic force on the moving positive charge?

Answer 1

the force is on the z axis, coming out of the blade

Step-by-step explanation:

The direction of the magnetic force is given by the right hand rule,

For a positive charge, the thumb points in the direction of velocity, the other fingers extended in the direction of the magnetic field, and the palm points in the direction of force.

In this case.

Thumb points North

The fingers extended is in the east - west direction parallel to the blade

The palm is sticking out of the leaf, in the z direction

the answer is the force is on the z axis, coming out of the blade
