### Magnetic Forces on a Moving Charge

A charge is moving perpendicular to a magnetic field and experiences a force whose magnitude is \(1.76 \times 10^{-3}\) N. If this same charge were to move at the same speed and the angle between its velocity and the same magnetic field were \(45.6^\circ\), what would be the magnitude of the magnetic force that the charge would experience?

#### Explanation
When a charged particle moves through a magnetic field, the force (\(F\)) it experiences is given by the equation:
\[ F = qvB \sin \theta \]

- \( q \) is the charge.
- \( v \) is the velocity of the charge.
- \( B \) is the magnetic field strength.
- \( \theta \) is the angle between the velocity and the direction of the magnetic field.

Given:
- Initial Force (\( F_1 \)) = \( 1.76 \times 10^{-3} \) N
- Initial Angle (\( \theta_1 \)) = \( 90^\circ \)
- Angle between velocity and magnetic field in the second scenario (\( \theta_2 \)) = \( 45.6^\circ \)

For \(\theta_1 = 90^\circ\),
\[ \sin 90^\circ = 1 \]

Thus, the force in the first scenario can be written as:
\[ F_1 = qvB \]

Now for the second scenario where \(\theta_2 = 45.6^\circ\),
\[ \sin 45.6^\circ = \sin(0.796 \, \text{radians}) \approx 0.714 \]

The magnitude of the new force (\( F_2 \)) is:
\[ F_2 = qvB \sin 45.6^\circ = F_1 \cdot \sin 45.6^\circ \]

Insert the values:
\[ F_2 = (1.76 \times 10^{-3} \, \text{N}) \cdot 0.714 \]
\[ F_2 \approx 1.25664 \times 10^{-3} \, \text{N} \]
