Jaclyn gets accepted to a PA school in Idaho. And when she arrives she realizes that no matter where she goes in the state she cannot find a good signal. To fix this problem, Jaclyn attaches a 2 m long antenna and attaches it to her iPhone. If the antenna carries a 900 µC charge, what will be the force on a 5 µC that is 30 cm (0.3 m) away from it's center?

A 4.3-MeV (kinetic energy) proton enters a 0.21-T field, in a plane perpendicular to the field.  What is the radius of its path?

The top of the atmosphere is at about 400 kV with respect to the surface of the earth, corresponding to an electric field that decreases with altitude. Near the surface of the earth, the field is about 100 Vm-1 Why then do we not get an electric shock as we step out of our house into the open? (Assume the house to be a steel cage so there is no field inside!)

A carbon-14 ion with a charge of +6.408x10^-19 C and a mass of 2.34x10^-26 kg is sent through a mass spectrometer and hits a detector at a point 10.0 cm to the left of  where the beam leaves the velocity selector. The velocity selector and the detector are both in a region of magentic field of strength 0.500 T.    If a carbon-12 ion (q=+6.408x10^-19 C, m= 1.99x10^-26 kg) is accelerated to the same velocity as the carbon-14 ion, where would you need to place the detector to detect it?   Please also explain and show the steps you used to get there/the physics behind why/how you got to the answer to help me better understand. Thank you soo much. Also, the work and the explanation or most important because I already have the correct answer - I'm just unsure of how to get there.

The Russian physicist P. A. C˘ erenkov discovered that a charged particle traveling in a solid with a speed exceeding the speed of light in that material radiates electromagnetic radiation. (This is analogous to the sonic boom produced by an aircraft moving faster than the speed of sound in air; see Section 16.9. C˘ erenkov shared the 1958 Nobel Prize for this discovery.) What is the minimum kinetic energy (in electron volts) that an electron must have while traveling inside a slab of crown glass (n = 1.52) in order to create this C˘ erenkov radiation?

Two neutral, square, thin copper plates (15 cm per side) are situated parallel to each other and located 6 mm apart.  A 9V battery is connected to the plates, such that the anode is connected to one plate and the cathode to the other plate, and the battery and plates reach a new electrostatic equilibrium. What is the magnitude and direction of the electric field between the two plates? Two neutral, square, thin copper plates (15 cm per side) are situated parallel to each other and located 6 mm apart.  A 9V potential difference is applied across the two plates. What is the electric potential at a distance of 2 mm away from the negatively charged plate (define the negative plate to be at zero potential)?

An electron of mass me = 9.11 × 10-³1 kg and a charge of - qe = -1.60 × 10-1⁹ C is released, from rest, in a region of uniform electric field that points to the right with a magnitude of |E| =5.55 N/C . How long does it take for the electron to reach a speed of 5.86 x 104 m/s? Assume the experiment is performed in a vacuum and that you can ignore the effects of gravity and friction.
