Find the GCF.

An electron is located on the x-axis at x0 = 1.55 × 10−6 m. Find the magnitude of the electric field at x = 4.07 × 10−6 m on the x-axis due to this electron.

A small plastic sphere of mass (m) has a charge q = 1.5 C. An upward pointing uniform electric field of magnitude 4.5 × 10-3 N/C supports and balances the weight of the sphere. Find the mass (m) of the sphere.

  An electron traveling to the right in a uniform magnetic field that points out of the page. While moving in this region, the electron’s path of motion will be

A capacitor has a capacitance of 70.0 μF. If you want to store 205 J of electric potential energy in this capacitor, what potential difference do you need to apply to the plates?

Two electrons a fixed distance apart, exert an electric force of 1.00 × 10-25 N on each other. What is the distance between these two point charges?  

A capacitor has a capacitance of 80.0 μF. If you want to store 155 J of electric potential energy in this capacitor, what potential difference do you need to apply to the plates?

What is the electric potential due to a 5.5 μC point charge at a distance of 0.95 cm, assuming the potential is zero as the distance approaches infinity.
