Q1. Determine the tension in each cable if the boat has a mass of 490 kg and the angle of each cable is 50 degrees from the horizontal and the boat is being momentarily held at rest. Evaluate this to the tension as the boat is raised and held at rest so the angle becomes 25 degrees.

Q2. Two infinite wires 20 cm apart each hold a current of 3 A into the paper. The acceleration of gravity is 9.8 m/s2 and the permeability of free space is 1.2566 × 10-6 N/A^2.At a distance d/2 below their midpoint, what is the magnitude of the magnetic field?
