Question

The drawing shows four situations in which a positively charged particle is moving with a velocity v through a magnetic field B. In each case, the magnetic field is directed out of the screen toward you, and the velocity is directed to the right. In only one of these drawings is the magnetic force F physically reasonable. Which one is it?

Answer 1

Option 1.

Step-by-step explanation:

The correct diagram can be determined by using the right hand rule. This can be used to estimate the of two vector forces. Therefore, the direction of the velocity v is to the right while that of the magnetic field B is out the plane. Since the in figure, we have a positively charged particle, the position of the magnetic force F is shown in option 1.
