A stationary metal conductor is carrying a current
in the direction to the right in the plane of the
paper as shown. It is in a region of uniform
magnetic field pointing perpendicularly into the
plane of the page. Which of the following
statements is correct?
a. P has a lower potential than Q
b. P and Q are at the same potential
c. P is at a positive potential
d. P has a higher potential than Q
(diagram given below)
- Fleming's Left Hand Rule
By using Fleming's Left Hand Rule, I got the force acting on proton is directed upwards so my answer is (d) but the answer key is (a). So the force acting on proton is actually downwards?
