WebFig. 10.2 shows an electric door lock. The slot in the door contains an unmagnetised iron bolt attached to a spring. The slot in the door frame is empty. This slot is surrounded by the coils of a solenoid. In Fig. 10.2 the door is unlocked. The spring is not stretched. The bolt is initially in the position shown in Fig. 10.2. Describe and ... WebA uniform plank AB of length 5.0 m and weight 200 N is placed across a stream, as shown in Fig. 3.1. A man of weight 880 N stands a distance x from end A. The ground exerts a vertical force FA on the plank at end A and a vertical force FB on the plank at end B. As the man moves along the plank, the plank is always in equilibrium.
