To determine The x-component of the force on the electron. Explanation Write the expression for x-component of force F = − d U d x (I) Here, U is the potential energy, F is the x-component of force and d x is the distance element. Write the given expression for potential U = 1.27 x 2 − 0.260 x 4 (II) Here, x is the position in nanometers. Substitute 1.27 x 2 − 0.260 x 4 for U in equation (I) F = − d ( ( 1.27 x 2 − 0.260 x 4 ) aJ ) d x = ( − 1.27 ( 2 x ) + 0

Simple harmonic motion

Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards…

Simple Pendulum

A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.

Oscillation

In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion tak…

Paraxial design of a field flattener. Imagine your optical system has Petzal curvature of the field with radius p. In Module 1 of Course 1, a homework problem asked you to derive the paraxial focus shift along the axis when a slab of glass was inserted in a converging cone of rays. Find or re-derive that result, then use it to calculate the paraxial radius of curvature of a field flattener of refractive index n that will correct the observed Petzval. Assume that the side of the flattener facing the image plane is plano. What is the required radius of the plano-convex field flattener? (p written as rho )
