The diagram shows a positive charge moving in a magnetic field.

in which direction is the magnetic force acting on the charge?

into the screen
out of the screen
up
down

Direction of force = Upwards

Explanation:

As we know that force on a moving charge in magnetic field is given by

now here we can see that positive charge is moving towards left in magnetic field which is coming out of the plane

so here

now by solving the equation we have

so the force is along +Y direction that is upwards

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
