1.	Both question a and b refer to the sustem of charges as shown in the figure. A spherical shell of conducting material. A point charge+Q is place at the centre of the spherical shell and a total charge -q is placed on the shell. A Charge -q id distributed on the surfaces as . (b) Assume that the elctrostatic potential is zero at an infinite distance from the spherical shell . The electrostatic potential at a distanceR (a lt R lt b) from the centre of the shell is .
Answer» `0` ` (KQ)/a` ` K (Q-q)/R` ` K(Q-q)/b (wnereK= (1)/(4 PI varepsilon_0))` Solution :(a) To. MAKE electric field indide metal charge on iner surface of shell must VBE equal to -Q ` V_p = (KQ)/R - (KQ)/R + (K(Q-q))/b = (K(Q-q))/b`

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
A concave lens with equal radius of curvature both sides has a focal length of 12 cm. The refractive index of the lens is 1.5. How will the focal length of the lens change if it is immersed in the liquid of refractive index 1.8 ?
