What is the expression for the tangential restoring force acting on a simple pendulum bob of mass mm when it is displaced by a small arc length ss from its equilibrium position? a) Ft=−mgLsF_t = -\dfrac{mgL}{s} b) Ft=−mgLsF_t = -\dfrac{mg}{L}s c) Ft=−12 mgLsF_t = -\dfrac{1}{2}\,\dfrac{mg}{L}s d) Ft=−mgsin⁡ ⁣(sL)F_t = -mg\sin\!\left(\dfrac{s}{L}\right)
