In a magnetic field, how does a point charge moving through it experience a force?
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?
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?
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)
- $\vec{g} = -\frac{GM}{r}\hat{r}$
- $\vec{g} = \frac{GM}{r^{2}}\hat{r}$
- $\vec{g} = -\frac{r^{2}}{GM}\hat{r}$
