Q1. 1. A wide, long, insulating belt has a uniform positive charge per unit area σ on its upper surface. Rollers at each end move the belt to the right at a constant speed v. compute magnitude and direction of magnetic field produced by the moving belt at a point just above its surface.

2. A very long cylindrical wire of radius R carries a current I_0 uniformly distributed across the section of the wire. Calculate the magnetic flux throughout a rectangle with a long side W running down the central axis of the wire, and a short side R

Q2. A scaffold of mass 42 kg and length 6.8 m is supported in a horizontal position by a vertical cable at each end. A window washer of mass 71 kg stands at a point 3.2 m from one end. What is tension in (a) the nearer (relative to the person) cable and (b) the farther (relative to the person) cable?

Q3. A projectile is fired at an upward angle of 45° from the top of a 237 m cliff with a speed of 179 m/s. What will be its speed as it strikes the ground below? (Make use of conservation of energy.)
