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 1.3 m. BP is perpendicular to AP, BP is an elastist
string of natural length im, while AP is an inelastic string of natural length 0.5m. P hangs igles
equilibrium when BP is 1.2m.
Taking g = 10ms 2 find
(a) the tension in each of the strings
(b) the modulus of elasticity of BP.
