Questions and Answers

In a magnetic field, how does a point charge moving through it experience a force?

$\vec{F} = q\vec{v}+\vec{B}$
$\vec{F} = q\vec{v}-\vec{B}$
$\vec{F} = q\vec{v}\cdot\vec{B}$
$\vec{F} = q\vec{v}\times\vec{B}$ (correct)

What is the force experienced by a point charge q in an electric field E?

$\vec{F} = q - \vec{E}$
$\vec{F} = q\vec{E}$ (correct)
$\vec{F} = \frac{q}{E}$
$\vec{F} = q + \vec{E}$

What is the gravitational force field created by a particle of mass M in Newtonian gravity?

$\vec{g} = -\frac{GM}{r^{2}}\hat{r}$ (correct)
$\vec{g} = -\frac{GM}{r}\hat{r}$
$\vec{g} = \frac{GM}{r^{2}}\hat{r}$
$\vec{g} = -\frac{r^{2}}{GM}\hat{r}$

What is a force field?

A vector field that exerts a non-contact force on particles at different positions in space.

Force on a point charge in an electric field

The force on a point charge q in an electric field E is given by $\vec{F} = q\vec{E}$

Force on moving charge in magnetic field

The force experienced is $\vec{F} = q\vec{v}\times\vec{B}$

Gravitational force field (Newtonian)

$\vec{g} = -\frac{GM}{r^{2}}\hat{r}$
