Moving Charges and Magnetism

  1. Two identical bar magnets are fixed with their centres at a distance d apart. A stationary charge Q is placed at P in between the gap of the two magnets at a distance D from the centre O as shown in the Figure​​

    The force on the charge Q is
    1. directed perpendicular to the plane of paper
    2. ​zero ​
    3. directed along OP
    4. directed along PO
Correct Option: B

​Force on a charged particle is given by F = qvB. Here v = 0 and also resultant B is zero. ​
∴ Force = 0
