Question
(a) along the +x direction
(b) along the -x direction
(c) along the +z direction
(d) along the -z direction
Part 2: The proton is replaced by a long, straight wire carrying a current in the +y direction as shown in figure 20.8B. Is the direction of the magnetic field at point A
(a) along the +x direction
(b) along the -x direction
(c) along the +z direction
(d) along the -z direction
Part 1: A proton travels at a constant velocity, with v directed along the +y direction as shown in Figure 20.8A. At a particular moment, the proton is at the origin. Is the direction of the magnetic field at point A (a) along the +x direction (b) along the -x direction (c) along the +z direction (d) along the -z direction Part 2: The proton is replaced by a long, straight wire carrying a current in the +y direction as shown in figure 20.8B. Is the direction of the magnetic field at point A (a) along the +x direction (b) along the -x direction (c) along the +z direction (d) along the -z directionExplanation / Answer
1.
as a moving charge can be treated as current then using right hand rule , direction of magnetic field is
(d) along the -z direction
2.
using right hand rule , here , we get diection of magnetic field as
(d) along the -z direction
