7. Figure 2 shows a mass P of 2.6kg, freely suspended by two strings AP and BP, fixed at two points
A and B on the same horizontal plane. AB is 13 m. BP is perpendicular to AP. BP is an elastina
string of natural length lm, while AP is an inelastic string of natural length 0.5m. P hangs in
equilibrium when BP is 1.2m.
