Q1.Two infinite wires 14 cm apart. The left-hand wire carries a current of 3 A into the paper. The right-hand wire carries a current of 3 A out of the paper. The permeability of free space 4pi x 10^-7 N/A^2 what is the magnitude of the force between these two wires.

Q2. A 66 N m torque acts on a wheel with a moment of inertia 175 kg m2. If the wheel starts from rest, how long will it take the wheel to make one revolution? The system is released from rest and accelerates under the weight of m2.

Q3. Ricardo, mass 83 kg and Carmelita, who is lighter, are enjoying Lake Merced at dusk in a 35 kg canoe. When the canoe is at rest in the placid water, they switch over seats that are 3.5 m apart and symmetrically located with respect to the center of the canoe. Ricardo notices that the canoe moved 54.3 cm relative to a submerged log during the exchange and calculates Carmelita's mass, that she has not told him. What is it?
