A circular table is rotating with an angular velocity of about its axis (see figure). There is a smooth groove along a radial direction on the table. A steel ball is gently placed at a distance of 1 m on the groove. All the surfaces are smooth. If the radius of the table is 3…

Question: A long straight wire carries a current, I=2 ampere. A semi-circular conducting rod is placed beside it on two conducting parallel rails of negligible resistance. Both the rails are parallel to the wire. The wire, the rod and the rails lie in the same horizontal plane, as shown in the figure. Two ends of the semi-circular rod are at distances 1 cm and 4 cm from the wire. At time t=0, the rod starts moving on the rails with a speed v=3.0 \mathrm{~m} / \mathrm{s} (see the figure).A resistor \mathrm{R}=1.4 \Omega and a capacitor \mathrm{C}_0=5.0 \mu \mathrm{~F} are connected in series between the rails. At time t=0, C_0 is uncharged. Which of the following statement(s) is(are) correct? [ \mu_0=4 \pi \times 10^{-7} SI units. Take \ln 2=0.7 ](2021)
