Figure shows a circular region of radius R− root 3 m which has a uniform magnetic field B = 0.2 T directed into the plane of the figure. A particle having mass m = 2 g, speed v = 0.3 m/s and charge q = 1 mC is projected along the radius of the circular region as shown in figure. Calculate the angular deviation produced in the path of the particle as it comes out of the magnetic field. Neglect any other force apart from the magnetic force.

A non-conducting rod having circular cross section of radius R is suspended from a rigid support as shown in fig. A light and small coil of 300turns is wrapped tightly at the left end where uniform magnetic filed B exists in vertically downward direction. Air of density ρ hits the half of the right part of the rod with velocity V as shown in the fig. What should be current in clockwise direction (as seen from O) in the coil so that rod remains horizontal? Give answer in mA.

A small coil C with N = 200 turns is mounted on one end of a balance beam and introduced between the poles of an electromagnet as shown in figure. The cross sectional area of coil is A = 1.0 cm^2, length of arm OA of the balance beam is l = 30 cm. When there is no current in the coil the balance is in equilibrium. On passing a current I = 22 mA through the coil the equilibrium is restored by putting the additional counter weight of mass Δm = 60 mg on the balance pan.
