Final answer:
To determine the mass of the suspended block E, we need to consider the forces acting on the system in equilibrium.
Explanation:
To determine the mass of the suspended block E, we need to consider the forces acting on the system in equilibrium. Since the system is in equilibrium, the sum of the forces in the vertical direction must be zero. We can start by analyzing the forces acting at point D. The weight of the 10 kg block acts downwards, and the tension in the cord acts upwards. Using the equation: Tension = mass x acceleration due to gravity, we can find the tension. Once we have the tension, we can use it to find the mass of block E by considering the forces at point E and point C.
