A) \[\left( \text{kJ mo}{{\text{l}}^{\text{-1}}} \right)\]
B) \[\left( \text{kJ mo}{{\text{l}}^{\text{-1}}} \right)\]
C) \[{{\left[ \text{Co}{{\left( \text{N}{{\text{H}}_{\text{3}}} \right)}_{\text{4}}}\text{C}{{\text{l}}_{\text{2}}} \right]}^{+}}\]
D) \[\text{I}\]
Correct Answer: D
Solution :
Let the velocity of wire is v at time t and the emf induced is\[{{R}_{1}}\], then charge (in magnitude) appeared on the plates of capacitor is \[{{R}_{2}}\] Now current, \[\frac{{{R}_{1}}}{{{R}_{2}}}\]\[\left| \frac{dL}{dt} \right|\] The force due to the current is \[2\,\,m\,\,{{l}^{3}}{{\omega }^{2}}\sin \theta .\cos \theta \] So, net force in the direction of motion of conductor wire \[\,m\,\,{{l}^{2}}{{\omega }^{2}}\sin 2\theta \] \[\,m\,\,{{l}^{2}}\sin 2\theta \]
