The figure shows the initial velocities of four identical positively charged particles in a uniform magnetic field. The square grid in the background can be used to infer the relative magnitudes of the velocities. The magnetic field is directed down the screen (in the negative y-direction). At the instant shown in the figure, in what direction is the force on particle 1?

Question
The figure shows the initial velocities of four identical positively charged particles in a uniform magnetic field. The square grid in the background can be used to infer the relative magnitudes of the velocities. The magnetic field is directed down the screen (in the negative y-direction). At the instant shown in the figure, in what direction is the force on particle 1? **Diagram Explanation:** - There is a grid with particles labeled 1, 2, 3, and 4, each having different initial velocities: - Particle 1 moves to the top right. - Particle 2 moves to the right. - Particle 3 moves down. - Particle 4 moves to the left. **Answer Choices:** - a) Up - b) Down - c) Left - d) Right - e) Into the screen - f) Out of the screen - g) A combination of two of the above **Instructions:** Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer.
