An electric charge moving past an observer will create:

When electric charge is placed at a point then it will produce electric field in the region surrounding the electric charge.

Similarly if the electric charge is in motion then rate of flow of charge will give electric current which is given as

also we know that steady flow of current will produce magnetic field in the region surrounding the current or moving charge.

Now here in this case an electric charge will pass through an observer due to which there exist the following effects

1). It will produce electric field surrounding the charge

2). moving charge will produce electric current

3). moving charge will also produce magnetic field in the surrounding of the electric charge when it is in motion

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

c) up is the direction the magnetic force is acting on the charge.
