उत्तर १
Fleming's left hand rule is used to determine the direction of force experienced by a current carrying straight conductor positioned perpendicular to a magnetic field. According to Fleming's left-hand rule, if the thumb, forefinger, and middle finger are stretched perpendicular to each other. If the thumb symbolises the direction of force, the forefinger represents the magnetic field, and the middle finger indicates the flow of current.
उत्तर २
- Fleming's Left-Hand Rule applies to calculating the force experienced by a current-carrying straight wire in a perpendicular magnetic field.
- According to Fleming's Left-Hand Rule, the thumb indicates force (F), the index finger indicates magnetic field (B), and the middle finger indicates current (I).
- Aligning the three directions according to the rule reveals the direction of the force exerted on the conductor.
- This law applies when the magnetic field, current, and force are perpendicular to one another.

The graph (fig A) illustrates the correlation between the number of protons (x-axis) and the number of neutrons (y-axis) for elements A, B, C, D, and E in the periodic table. These elements are denoted by the letters rather than their conventional symbols. When the element C, depicted in the graph, undergoes radioactive decay, it releases radioactive rays. When these rays are directed into the plane of the paper in the presence of a magnetic field, as indicated in the fig B, they experience deflection, causing them to move upwards.
