1.	A uniform cube of mass 4kg and side 30cm is placed on a fricitionless horizontal surface. A vertical force F is applied to the edge as shown in the figure. Choose the most appropriate option(s). (take g=10m//s^(2))
Answer» Cube will move in the upward direction if `F gt 40 N` Cube will not perform any type of TRANSLATION or roataion motion if `10N LT F lt 20N` Cube will begin to perform rotational motion if `20 N lt F lt 40N` Normal REACTION applied by the surface shifts to a distance `5cm` from CENTRE `C` of the cube if `F=10N` Solution :Momentum of segment of mass `dm` and length `dl` `dvecp=d "mu"(costhetahati+sinthetahatj)` `=u LAMBDA[dlcosthetai+dlsinthetahatj]` `vecP=mu lambda[intdxhati+intdyhatj]` `vecp=u lambda[dhati+hhatj]` `P=u lambdasqrt(d^(2)+h^(2))` `=1xx1sqrt(3^(2)+4^(2))=5kg-m//s`

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 ?
