Answer:
2069.76 N
Explanation:
density of wood = 824 kg/m^3
density of water = 1000 kg/m^3
Volume of wood = 1.2 m^3
True weight of wood = volume of wood x density of wood x gravity
True weight of wood = 1.2 x 824 x 9.8 = 9690.24 N
Buoyant force acting on wood = volume of wood x density of water x gravity
Buoyant force acting on wood = 1.2 x 1000 x 9.8 = 11760 N
Tension in the rope = Buoyant force - True weight
tension in rope = 11760 - 9690.24 = 2069.76 N
