A small solid ball is released from rest while fully sub merged in a liquid and then its kinetic energy is measured when it has moved 2.0 cm in the liquid. Figure 14.46 gives the results after many liquids are used: The kinetic energy K is plotted versus the liquid density rho_(liq) and K_(s) = 2.4 J sets the scale on the vertical axis. What are (a) the density and (b) the volume of the ball?

1.	A small solid ball is released from rest while fully sub merged in a liquid and then its kinetic energy is measured when it has moved 2.0 cm in the liquid. Figure 14.46 gives the results after many liquids are used: The kinetic energy K is plotted versus the liquid density rho_(liq) and K_(s) = 2.4 J sets the scale on the vertical axis. What are (a) the density and (b) the volume of the ball?
Answer» Solution :(a) `1.5 g//cm^(3)` (or 1500 kg /`m^(3)) , (b) 8.16 XX 10^(-3) m^(3)` (or `8.16 xx 10^(-3) m^(3)` in TWO SIGNIFICANT digits)

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 ?
