Question
Chapter 9, Problem 1Q
To determine
The reason behind the opposite direction of orbital
Expert Solution & Answer
Answer to Problem 1Q
The direction of magnetic moment and orbital angular momentum of a charged particle depends upon the polarity of the charge on the charged particle. The electron is a negatively charged particle due to which the direction of magnetic moment is opposite to that of the direction of orbital angular momentum.
Explanation of Solution
The orbital angular moment of an electron arises due to the motion of the electron about its nucleus. The orbital angular momentum is rotational variant of linear angular momentum.
The magnetic moment or magnetic dipole moment of an electron arises due to the intrinsic properties of electron mainly charge and spin.
Write the expression for the magnetic moment of a charged particle.
Here,
The direction of magnetic moment and orbital angular momentum of a charged particle depends upon the polarity of the charge on the charged particle. The electron is a negatively charged particle due to which the direction of magnetic moment is opposite to that of the direction of orbital angular momentum.
Conclusion:
Thus, the direction of magnetic moment and orbital angular momentum of a charged particle depends upon the polarity of the charge on the charged particle. The electron is a negatively charged particle due to which the direction of magnetic moment is opposite to that of the direction of orbital angular momentum.

The rectangular loop of wire shown in the figure (Figure 1) has a mass of 0.18 g per centimeter of length and is pivoted about side ab on a frictionless axis. The current in the wire is 8.5 A in the direction shown. Find the magnitude of the magnetic field parallel to the y-axis that will cause the loop to swing up until its plane makes an angle of 30.0 ∘ with the yz-plane. The answer is .028 T, I just need help understanding how to do it. Please show all steps.
A ray of light from an object you want to look at strikes a mirror so that the light ray makes a 32 degree angle relative to the normal line (a line perpendicular to the surface of the mirror at the point where the ray strikes the mirror). If you want to see the object in the mirror, what angle does your line of sight need to make relative to the normal line? Give your answer as the number of degrees.
