Problem-Solving Strategy: Direction of the Magnetic Field by the Right-Hand Rule The direction of the magnetic force F → is perpendicular to the plane formed by v → and B → as determined by the right-hand rule-1 (or RHR-1), which is illustrated in Figure 11.3. 1. WebThe dust particles were brought together by the forces of drag to form clumps of rock that grew into “planetesimals” tens to hundreds of miles across, and then to Mars-sized “protoplanets” by colliding with each other. Earth grew to its final size through one last major collision with another Mars-sized object.
