Answer to Problem 1P

Correct choice is (b)

Explanation of Solution

Introduction:

Magnetic force on a moving charged particle moving through a magnetic field region is given as

  Fb=q(v×B)

Clearly, the direction of deflection of the charged particle is given by the direction of the cross-product of velocity of the charged particle and magnetic field vector.

Direction of deflection of the electron is same as the direction of the magnetic force on it. For a positive charge, the direction of deflection is same as you get for the magnetic force using right hand rule but for a negative charge, the direction of deflection is opposite to the direction of magnetic forceyou will get using right hand rule.

Conclusion:

Hence, correct choice of path is (b)
