Answer: Ok so We already know that velocity is on the x-axis.
Since acceleration = Force / Mass
Here the Force is downward due to the gravitational pull or we can say it is along y-axis.
Since acceleration is directly proportional to force, so acceleration is also along y-axis. This means that velocity & acceleration are perpendicular to each other.
Example:
Let us assume that an aeroplane is flying parallel to the horizontal plane. The aeroplane will experience the acceleration in several directions. One of them here is the gravitational pull which is perpendicular to the the apparent velocity. So the net velocity & its direction will depend upon the vector sum total of all the forces/acceleration acting on it. Also because of this gravitational pull the aeroplane rotates along with the earth, which is a proof that the force/g experienced by it does not go waste.

Answer:
The magnitude of magnetic field is 0.312 T and direction of the magnetic field is out of the page.
Explanation:
Given:
Velocity of proton
Magnetic force N
Charge of proton C
The magnetic force experience by proton in magnetic field is given by,
Here magnetic force experienced by proton is maximum so we take
T
According to the left hand rule the direction of magnetic field is out of the page.
Therefore, the magnitude of magnetic field is 0.312 T and direction of the magnetic field is out of the page.
