1. If an electron is travelling horizontally towards east, a magnetic field in vertically downward direction exerts a force on the electron along *1 point east west north south.

The force exerted by a magnetic field on a moving charged particle can be determined using the right-hand rule. In this case, since the electron is moving horizontally towards the east and the magnetic field is vertically downward, we can use the right-hand rule to determine the direction of the force.

To do this, we extend our right hand with the thumb pointing in the direction of the electron's velocity (east) and the fingers pointing in the direction of the magnetic field (downward). The palm of our hand will then indicate the direction of the force.

In this case, the force will be directed towards the south. Therefore, the correct answer is south.

2. If a charged particle is moving along a magnetic field line, the magnetic force on the particle is *1 point along its velocity opposite to its velocity perpendicular to its velocity Zero.

When a charged particle moves along a magnetic field line, the magnetic force acting on it will be perpendicular to both the velocity of the particle and the magnetic field. This can be determined using the right-hand rule.

To determine the direction of the force, we extend our right hand with the thumb pointing in the direction of the particle's velocity and the fingers pointing in the direction of the magnetic field. The palm of our hand will then indicate the direction of the force.

In this case, the force will be perpendicular to the velocity of the particle. Therefore, the correct answer is perpendicular to its velocity.

3. A magnetic field exerts no force on *1 point a stationary electric charge a magnet an electric charge moving perpendicular to its direction a non-magnetized iron bar.

A magnetic field exerts a force only on moving charged particles. Therefore, a stationary electric charge will not experience any force from a magnetic field. Therefore, the correct answer is a stationary electric charge.

4. An electron beam enters a magnetic field at right angles to it as shown in the figure. The direction of force acting on the electron beam will be *1 point To the left to the right into the plane out of the plane.

When an electron beam enters a magnetic field at right angles to it, the force acting on the electron beam can be determined using the right-hand rule.

To determine the direction of the force, we extend our right hand with the thumb pointing in the direction of the electron beam's velocity and the fingers pointing in the direction of the magnetic field. The palm of our hand will then indicate the direction of the force.

In this case, the force will be directed out of the plane. Therefore, the correct answer is out of the plane.
