A thin lens made of a material of refractive index mu_2 has a medium of refractive index mu_1 on one side and a medium of refractive index on the other side. The lens is biconvex and the two radii of curvature have equal magnitude R. A beam of light travelling parallel to the principal axis is incident on the lens. Where will the image be formed if the beam is incident from (a) the medium p, and (b) from the medium mu_3 ?

Separation of Motion of a system of particles into motion of the centre of mass and motion about the centre of mass : (a) Show p=p_(i)'+m_(i)V where pi is the momentum of the ith particle (of mass m_(i) ) and p'_(i)=m_(i)v'_(i) . Note v'_(i) is the velocity of the ith particle relative to the centre of mass. Also, prove using the definition of the centre of mass sump'_(i)=O (b) Show K=K'+1//2MV^(2) where K is the total kinetic energy of the system of particles, K′ is the total kinetic energy of the system when the particle velocities are taken with respect to the centre of mass and MV^(2)//2 is the kinetic energy of the translation of the system as a whole (i.e. of the centre of mass motion of the system). The result has been used in Sec. 7.14. (c ) Show L=L'+RxxMV where L'=sumr'_(i)xxp'_(i) is the angular momentum of the system about the centre of mass with velocities taken relative to the centre of mass. Remember – r'_(i)=r_(i)-R , rest of the notation is the standard notation used in the chapter. Note ′ L and MR × V can be said to be angular momenta, respectively, about and of the centre of mass of the system of particles. (d) Show (dL')/(dt)=sumr'_(i)xx(dp')/(dt) Further, show that (dL')/(dt)=tau'_(ext) where tau'_(ext) is the sum of all external torques acting on the system about the centre of mass.

Magnetic scalar potential is defined as U(vec r_2) - U vec (r_1) = - int_vec(r_1) ^vec(r_2) vecB.vec(dl) Apply this equation to a closed curve enclosing a long straight wire. The RHS of the above equation is then mu_0 i by Ampere's law. We see that U vec r_2) != U(vec r_1) even when vec r_2 = vec r_1 . Can we have a magnetic scalar potential in this case.?

In Ampere's law (oint (vec B).(vec dl))=(mu_0)I , the current outside the curve is not included on the right hand side. Does it mean that the magnetic field B calculated by using Ampere's law , gives the contribution of only the currents crossing the area bounded by the curve?

For a circular coil of radias R and N turns carrying current I, the magnitude of the magnetic field at a point on its at a distance x from its centre is given by B=(mu_0 IR^2 N)/(2(x^2+R^2)^(1/2)) a. Show that this reduces to the familar result for field the centre of the coil . ]

Consider a DeltaABC in which sides AB and AC are perpendicular to x-y-4=0 and 2x-y-5=0, repectively. Vertex A is (-2, 3) and the circumcenter of DeltaABC is (3/2, 5/2). The equation of the line in List I is of the form ax+by+c=0, where a,b,c in I. Match it with the corresponding value of c in list II and then choose the correct code.
