Answer: Acceleration is a measure of how fast velocity changes. Acceleration is the change of velocity divided by the change of time. Acceleration is a vector, and therefore includes both a size and a direction. In short, acceleration is the rate at which speed changes.
Answer:
Positive z direction.
Explanation:
The magnetic force acting on the electron is given by the formula as :
![F=q(v\times B)](https://tex.z-dn.net/?f=F%3Dq%28v%5Ctimes%20B%29)
q is the charge on proton
v is the speed of proton
B is the magnetic field
It is mentioned that the proton is moving with a velocity in the positive x-direction. The uniform magnetic field B in the positive y-direction such taht,
q = +e
v = vi
B = Bj
![F=e(v\ i\times B\ j)](https://tex.z-dn.net/?f=F%3De%28v%5C%20i%5Ctimes%20B%5C%20j%29)
Since, ![i\times j=k](https://tex.z-dn.net/?f=i%5Ctimes%20j%3Dk)
![F=(evB)\ k](https://tex.z-dn.net/?f=F%3D%28evB%29%5C%20k)
So, the magnetic force acting on the proton in positive z axis. Hence, the correct option is (d) "positive z direction".
