Indicate true or false in each of the following statements:

1. A static magnetic field can do work on a current carrying wire when the current in the wire is perpendicular to the field.
2. The time required for a charged particle to complete one cycle of a circular path in a uniform magnetic field is independent of the velocity of the charged particle.
3. The magnetic field lines leave the north pole of a bar magnet and enter the south pole and are continuous inside the magnet.
4. A charged particle moving perpendicular to a uniform B field will move on a spiral path.
5.Two antiparallel currents repel each other.
1.True 2.True 3.true 4.false( circular path) 5.true

2. Ignoring relativistic mass, you are right. In the real world, mass is dependent on velocity.
