A proton (e) appronches a short fixed electric dipole (p) moving along the dipole axis as shown in the figure. At a large distance from the dipole, the kinetic energy of the proton was K0 = 400 eV. The graph below shows the variation of kinetic energy (K) of the proton at points close to the dipole. Find the value of ro0 ( ro0≫ length of the dipole). In the graph r is the distance from the centre of the dipole.

A proton moving in the plane of the page has a kinetic energy of 5.92 MeV. It enters a magnetic field of magnitude B = 1.15 T directed into the page, moving at an angle of θ = 45.0 deg with the straight linear boundary of the field, as shown in the figure below. Calculate the distance x from the point of entry to where the proton leaves the field. Determine the angle between the boundary and the proton's velocity vector as it leaves the field.

Let us assume a stream of non-relativistic electrons of kinetic energy E travelling along the x-axis experiences an abrupt change in potential from 0 to V1 at x = 0, where E > V1. At x = a, the electrons experience another step change in potential from V1 to V2, as shown in the sketch below. (a) Starting from the "time independent" Schrödinger equation for the particle wavefunctions in different regions (i. e. x < 0, 0 < x < a and x > a), write down the general solutions for the allowed eigenfunctions. (b) Draw a suitably labelled diagram to appropriately represent the eigenfunctions in all regions. (c) Using appropriate boundary conditions to ensure the eigenfunctions are well behaved, show that there will be 100% transmission of electrons to the region x > a when V2 = 0 and that the wavelength of the eigenfunction in the region 0 < x < a is 2a.

Two rods are placed in x−y plane as shown in figure. The right rod has a length of 2 m and a uniform positive total charge of 7 μC. It is placed with its nearest end at a distance 0.5 m from the origin and the axis of the rod makes an angle of 60∘ with the y-axis. The left rod has a length of 3 m, and a uniform negative total charge −12 μC. It is placed with its nearest end at a distance 0.4 m from the origin the axis of the rod makes an angle of 60∘ with the y -axis as shown in figure. Calculate the magnitude and direction of the electric field at the origin due to both rods.
