Acharge of 1.5 × 1015 coulombs moves from point a to a lower potential at point b. the electric field is uniform at 2.5 × 10-5 newtons/coulomb and the distance along the field lines between the two points is 1.7 × 10-2 meters. what is the work done? 1.5 × 10-12 joules

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
