In a region of space, a uniform electric field of strength E, a uniform magnetic field of induction B and a uniform gravitational field of strength g coexist in mutually perpendicular directions. A charge particle is moving with a uniform velocity in this region. Once the particle leaves this region and begins moving into another region where there is only gravitational field of strength g, its speed begins to decrease. How long after departure from the first region, will the velocity of the particle become minimum? Av; E

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
