In a Newton's ring experiment, a plano- convex glass (n = 1.42) lens having diame- ter 11.8 cm is placed on a flat plate as in the figure. When 682 nm light is incident normally, 7 bright rings are observed with the last one right on the edge of the lens, at r.
a) What is the radius of curvature of the convex surface of the lens?
b) What is the focal length of the lense?
A small block with a mass of 0.170 kg is attached to a cord passing through the hole in a frictionless, horizontal surface .The block is initially revolving at a distance of 0.50 m from the hole with a speed of 0.80 m/s. The cord is then pulled from ..
A uniform electric field of magnitude 380 N/C pointing in the positive x-direction acts on an electron, which is initially at rest. The electron has moved 2.60 cm. What is the work done by the field on the electron
