The magnetic field at the equator points north. if you throw a positively charged object (for example, a baseball with some electrons removed) to the east, what is the direction of the magnetic force on the object
F = qv x B *x is cross product, not separate variable!
If the magnetic field points towards N and you throw E, then the magnetic force would point up, or out of the page. Use the right-hand rule. You point your finger towards the direction of the object, and curl your finger to the magnetic field. Your thumb is the direction of the magnetic force.
