Apoint charge of 6.0 c is placed 5.0 mm from a rod that has an electric field of 2.4 n/c. the electric potential energy of the point charge (rounded to two significant figures) is .

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
