What is the speed of a proton that has been accelerated through $2300\mathrm{V}$?

INT CALC Two positive point charges q are located on the y-axis at y = ±a.e. Your answer to part d shows that an electron experiences a linear restoring force, so it will undergo simple harmonic motion. What is the oscillation frequency in GHz for an electron moving between two 1.0 nC charges separated by 2.0 mm?

The x component of a uniform electric field is ${\mathrm{E}}_{\mathrm{x}}=12\mathrm{V}/\mathrm{m}$. What is the potential difference between ${\mathrm{x}}_{\mathrm{i}}=45\mathrm{m}$ and ${\mathrm{x}}_{\mathrm{f}}=12\mathrm{m}$?

The electric potential in a region of uniform electric field is $1200\mathrm{V}$ at $\mathrm{x}=-4.3\mathrm{m}$ and $2800\mathrm{V}$ at $\mathrm{x}=2.1\mathrm{m}$. What is ${\mathrm{E}}_{\mathrm{x}}$?

Point A is at $-25\mathrm{V}$ and point B is at $400\mathrm{V}$. A proton moves past point A at $3.5\times {10}^5\mathrm{m}/\mathrm{s}$, what is its speed when it reaches point B?

The water molecule is a permanent electric dipole with a dipole moment of $6.2\times {10}^{-30}\mathrm{C}\mathrm{m}$. A water molecule is aligned with an electric field of magnitude $7600\mathrm{V}/\mathrm{m}$. How much energy is required to rotate the molecule 180°?

A student wants to make a very small particle accelerator using a 9.0 V battery. What speed will (b) an electron have after being accelerated from rest through the 9.0 V potential difference?

A 3.0-cm-diameter parallel-plate capacitor has a 2.0 mm spacing. The electric field strength inside the capacitor is 1.0×10^5 V/m.a. What is the potential difference across the capacitor?
