As shown in the figure,$P$ and $Q$ are two coaxial conducting loops separated by some distance. When the switch $S$ is closed, a clockwise current ${I_P}$ flows in $P$ (as seen by $E$) and an induced current ${I_{{Q_1}}}$ flows in $Q.$ The switch remains closed for a long time. When $S$ is opened, a current ${I_{{Q_2}}}$ flows in $Q$. Then the directions of ${I_{{Q_1}}}$ and ${I_{{Q_2}}}$ (as seen by $E$) are

Starting from rest on her swing at initial height $h_0$ above the ground, Saina swings forward. At the lowest point of her motion, she grabs her bag that lies on the ground. Saina continues swinging forward to reach maximum height $h_1$ . She then swings backward and when reaching the lowest point of motion again, she simple lets go off the bag, which falls freely. Saina's backward swing then reaches maximum height $h_2$ . Neglecting air resistance, how are the three heights related?
