When yellow light with a wavelength of 589 nm enters from the air into a transparent plastic body at an inlet angle of 20.0 °, the angle of refraction is 13.3 °. Count
- refractive index of plastic
- wavelength of light in plastic.
We have the one plate charged to 5.0 nano coulomb and the other one. Exactly equal but opposite.
An additional square shaped surface is placed in between plates
12 infinite lines of charge each with -λ are equally spaced and fixed around a circle of radius R. A proton (of charge +e) is located at the center of the circle. Now, the line charge at the 6 o'clock position is removed from the charge configuration leaving the others fixed. What is the magnitude of the net force on the proton?
Consider the configuration of three point charges (all having the same charge) forming a equilateral triangle (all sides have length a) in the x-y plane. Assume that all three charges are released from rest at the same time. When the charges are far away from each other. What is their total kinetic energy ?
