Answer 1

The acceleration of a proton at rest depends on its initial velocity and the direction and magnitude of the magnetic field.

Step-by-step explanation:

In order to answer these questions, we need to consider the relationship between magnetic field and acceleration.

1. At point A, the proton is at rest. Therefore, its acceleration is zero (a=0).

2. The direction of the acceleration of a proton at rest at point A is horizontally to the left (d. horizontally to the left).

3. At point B, the acceleration can be found using the equation a = B * v, where B is the magnetic field strength and v is the velocity of the proton. The magnitude of the acceleration at point B is 0.7 m/s2.

4. The direction of the acceleration of a proton at rest at point B is horizontally to the left (d. horizontally to the left).

5. At point C, since the proton is moving with a constant velocity perpendicular to the magnetic field, its acceleration is zero (a=0).

6. The direction of the acceleration of a proton at rest at point C is horizontally to the left (d. horizontally to the left).

7. At point D, the proton is moving in the opposite direction of the decreasing magnetic field. Therefore, its acceleration is zero (a=0).

8. The direction of the acceleration of a proton at rest at point D is horizontally to the left (d. horizontally to the left).

Answer 2

The magnitude of the acceleration of a proton at rest at point a is 0. The magnitude of the acceleration of a proton at rest at point b is also 0. The magnitudes and directions of the accelerations at points c and d are not provided.

Step-by-step explanation:

In the figure, point A represents a location where the magnetic field is decreasing. When a proton is at rest at point a, it will experience zero acceleration because it is not moving. Therefore, the magnitude of the acceleration of a proton at rest at point a is a = 0. The direction of the acceleration is not applicable because there is no acceleration.

Similarly, when a proton is at rest at point b, it will also experience zero acceleration because it is not moving. The magnitude of the acceleration of a proton at rest at point b is a = 0. The direction of the acceleration is not applicable because there is no acceleration.

At point c, the magnetic field is increasing, not decreasing. Therefore, the magnitude of the acceleration of a proton at rest at point c is not provided in the given information. The direction of the acceleration is also not provided in the given information.

Similarly, at point d, the magnetic field is also increasing. Therefore, the magnitude of the acceleration of a proton at rest at point d is not provided in the given information. The direction of the acceleration is also not provided in the given information.
