Question
Chapter 4, Problem 1CQ
To determine
Reason why the muzzle of a rifle is not aimed at the centre of the target. The reason why this is more important for longer ranges.
Expert Solution & Answer
Answer to Problem 1CQ
The muzzle of a rifle is not directly aimed at target to compensate the effect of gravity. For longer range it is more important as gravity gets longer time to affect the path of the bullet.
Explanation of Solution
While travelling from the muzzle to rifle towards the target, the bullet is influenced by gravity. Gravitational force accelerates the bullet down. If the bullet is pointed directly, the acceleration due to gravity will cause the bullet land below the target. Thus the muzzle of a rifle is not aimed directly at the centre of the target.
When the range of the bullet is long, the time spent in air is proportionally longer, gravity will no longer influence bullet’s path. Therefore, for a longer path it is more important to not to aim directly at the target, but at a suitable point land exactly on the target.
Conclusion
The muzzle of a rifle is not directly aimed at target to compensate the effect of gravity. For longer range it is more important as gravity gets longer time to affect the path of the bullet.

Two moving charged particles exert forces on each other because each creates a magnetic field that acts
on the other. These two "Lorentz" forces are proportional to vix (2 xr) and 2 x (vi x-r), where is the vector
between the particle positions. Show that these two forces are equal and opposite in accordance with Newton's third
law if and only if rx (vi × 2) = 0.

During the one-armed maneuver first developed in the 1940s, the outstretched arm of the male skater must apply a large force to support a significant fraction of the female skater's weight and also to provide her centripetal acceleration.
