You will notice that the tool is designed with a built-in pivot point about which the torques are applied. If the gardener applies a 1.85 N · m torque (about the pivot point) in order to pull a weed, determine the resistive force (in N) the weed exerts on the weed puller.

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
