Protons and singly ionized atoms of U^(2...

Protons and singly ionized atoms of `U^(235)` & `U^(238)` are passed in turn (which means one after the other and not at the same time) through a velocity selector and then enter a uniform magnetic field. The protons describe semicircles of radius `10 mm`. The separation between the ions of `U^(235)` and `U^(238)` after describing semicircle is given by

An electron moving with a speed u along the positive x-axis at y=0 enters a region of uniform magnetic field which exists to the right of y-axis. The electron exits from the region after some time with the speed v at coordinate y, then

Two stars bound together by gravity orbit othe because of their mutual attraction. Such a pair of stars is referred to as a binary star system. One type of binary system is that of a black hole and a companion star. The black hole is a star that has cullapsed on itself and is so missive that not even light rays can escape its gravitational pull therefore when describing the relative motion of a black hole and companion star, the motion of the black hole can be assumed negligible compared to that of the companion. The orbit of the companion star is either elliptical with the black hole at one of the foci or circular with the black hole at the centre. The gravitational potential energy is given by U=-GmM//r where G is the universal gravitational constant, m is the mass of the companion star, M is the mass of the black hole, and r is the distance between the centre of the companion star and the centre of the black hole. Since the gravitational force is conservative. The companion star and the centre of the black hole, since the gravitational force is conservative the companion star's total mechanical energy is a constant. Because of the periodic nature of of orbit there is a simple relation between the average kinetic energy ltKgt of the companion star Two special points along the orbit are single out by astronomers. Parigee isthe point at which the companion star is closest to the black hole, and apogee is the point at which is the farthest from the black hole. Q. For circular orbits the potential energy of the companion star is constant throughout the orbit. if the radius of the orbit doubles, what is the new value of the velocity of the companion star?

A proton enters a region of uniform magnetic field B of 0.5T with a velocity u at an angle 45^(@) with B .If P is the pitch of the helical path followed,the radius of the helix is :?

Two cacar starts together from the asme point and move along two straight lines inclined at an angle theta , one moving with velocity (u) and the other from rest with a uniform acceleration (a). Show that the least relative velocity between then is u sin theta and it occurs after a time t= ( u cos theta) //a .
