Final answer:
The tension in one chain of the chandelier can be found using Newton's second law. The expression for the magnitude of the tension in terms of mass and gravitational acceleration is T = 6.5 kg * g.
Step-by-step explanation:
The tension in each chain can be found using Newton's second law. The tension in one chain is equal to the weight of the chandelier which is given by the formula T = m * g, where T is the tension, m is the mass of the chandelier, and g is the gravitational acceleration on the Earth's surface. Therefore, the expression for the magnitude of the tension in one chain in terms of m and g is T = 6.5 kg * g.
