A charge of 8.5 x 10^-6 is in an electric field that has a strength of 3.2 x10^5 what is the electric force

Consider a thin plane-parallel layer of air contained between two thick
expanses of glass. A plane wave is propagating in one of the glass regions
at an angle of 60◦ with respect to the normal at the glass-air interface.
Take the glass refractive index to be 1.46.
For these conditions, calculate and plot the parallel and perpendicular
reflectivity of the glass-to-air interface as a function of the dimensionless
air layer thickness k0h. Discuss why the reflectivity is such a sensitive
function of the thickness

Obtain expressions for reflection and transmission amplitude coefficients when electric vector associated with a plane monochromatic electromagnetic wave is in the plane of incidence

masie was asked to go find out what affects the strength of electromagnets. she was given a simple electromagnet made from a coil of wire and a power supply
What variables could masie investigate?
form a question for masie to investigate

two charges q1 and q2 are separated by a distance d. if the distance is doubled the electric potential is

A small particle has charge -5uC and mass 2x10^-4kg. It moves from point A, where the electric potential is Va=+200V, at point B is Vb=+800V. The electric force is the only electric force acting on the particle. The particle has speed 5m/s at point A. What is the speed at point B?

suppose that electric field in some region is found to have a constant directionbut to be decreasin in streanght in that direction what do you conclude about the chargein the region
