A proton entering a uniform magnetic field B in the direction of B will move along a:
Correct answer: A. Straight line
- A. Straight line
- B. Circle
- C. Parabola
- D. Helix
Explanation
FB = qvBsin0o = 0 So, proton will move along the straight lline.If the proton enters in the magnetic field in the direction of the field then the angle between v and B would be 0 and sin(0)=0 so the proton will move in the straight line.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
