Two identical conductors \( P \) and \( Q \) are placed on two
frictiônless fixed conducting rails \( R \) and \( S \) in a uniform
magnetic field directed into the plane. If \( P \) is moved in
the direction shown in figure with a constant speed,
then rod \( Q \)
(1) will be attracted towards P
(2) will be repelled away from \( P \)
(3) will remain stationary
(4) may be repelled or attracted towards P
