Question

A proton moving vertically downward enters a magnetic field pointing towards north. In which direction proton will deflect?
  1. East
  2. West
  3. North
  4. South

A
South
B
West
C
East
D
North
Solution
Verified by Toppr

Proton will represent the direction of current. So, the direction of current is vertically downward. According to Fleming's left hand rule, if middle finger represents the direction of current and fore-finger represents the direction of magnetic field then thumb will represent the direction of Lorentz force acting on the proton which deflects the proton in east direction.
Hence, option A is correct.

Assertion :A proton moves horizontally towards a vertical long conductor having an upward electric current. It will deflect vertically downward. Reason: Seeing the proton and the conductor from the side of the proton, the magnetic field at the site of the proton will be be towards right. Hence the force F=qv×B will deflect the proton vertically downward.
