A bead of mass 100 g is attached to one end of a spring of natural length L and spring constant k=((sqrt3+1)mg)/L, where m is the mass of bead. The other end of the spring is fixed at point A on a smooth vertical ring of radius R as shown in the figure. The normal reaction at B just after it is released to move is (take, g=9.8ms^(-2))

1.	A bead of mass 100 g is attached to one end of a spring of natural length L and spring constant k=((sqrt3+1)mg)/L, where m is the mass of bead. The other end of the spring is fixed at point A on a smooth vertical ring of radius R as shown in the figure. The normal reaction at B just after it is released to move is (take, g=9.8ms^(-2))
Answer» 1.73 N 2.23 N 2.44 N 2.55 N Solution :NORMAL REACTION = Resultant of spring FORCE kx and weight mg. = `sqrt((K^(2)x^(2)+m^(2)G^(2)))=2.55N`

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
