    Given below are two statements : Statement I: A satellite is moving around earth in the orbit very close to the earth surface. The time period of revolution of satellite depends upon the density of earth. Statement II : The time period of revolution of the satellite is T=2πRegT = 2\pi\sqrt{\frac{R_{e}}{g}} (for satellite very close to the earth surface), where ReR_{e} radius of earth and gg acceleration due to gravity. In the light of the above statements, choose the correct answer from the options given below :

    Given below are two statements : Statement I: An object moves from position r1r_{1} to position r2r_{2} under a conservative force field F→\overrightarrow{F}. The work done by the force is W=−∫r1r2F→⋅dr→W = - \int_{r_{1}}^{r_{2}} \overrightarrow{F} \cdot \overrightarrow{dr}. Statement II : Any object moving from one location to another location can follow infinite number of paths. Therefore, the amount of work done by the object changes with the path it follows for a conservative force. In the light of the above statements, choose the correct answer from the options given below :

    Three identical coils C1,C2C_{1},C_{2} and C3C_{3} are closely placed such that they share a common axis. C2C_{2} is exactly midway. C1C_{1} carries current II in anti-clockwise direction while C3C_{3} carries current II in clockwise direction. An induced current flows through C2C_{2} will be in clockwise direction when
