Answer:
The correct option is option 5
Explanation:
From the question we are told that the positive particle is stationary hence the velocity is zero
Generally the magnetic force acting on the particle is mathematically represented as
[tex]\vec F = Q \vec v \ \ X \ \vec B[/tex]
Here X represents a cross product
So since the velocity is zero
[tex]\vec F = Q (0) \ \ X \ \vec B[/tex]
[tex]\vec F = 0[/tex]

The direction of the magnetic force on the particle is zero.
What is magnetic force?
It is treated as the attraction that occurs between electrically charged particles due to motion. It is the basic force that should be responsible for effects. Here the positive particle should be stationary so the velocity should be zero
hence, we can conclude that The direction of the magnetic force on the particle is zero.
