1.	The velocity of a body of mass 2 kg is given byvecupsilon=(2t overset(wedge)(i)+t^(2)overset(wedge)(j))Find the momentum of the body after 2 seconds.
Answer» `(8overset(wedge)(i)+8overset(wedge)(j))KG ms^(-1)` `(4overset(wedge)(i)+4overset(wedge)(j))kg ms^(-1)` `(6overset(wedge)(i)+6overset(wedge)(j))kg ms^(-1)` `(10overset(wedge)(i)+10overset(wedge)(j))kg ms^(-1)` SOLUTION :Here mass of the body = 2kg `vecupsilon=(2thati+t^(2)hatj)` velocity after 2 sec `vecupsilon`= `vecupsilon_(t)=(2xx2hati+4hatj)` `(4hati+4hatj)` MONENTUM`vecp_(t)=m vecupsilon_(t)` `=2(4hati+4hatj)`Hence (a) is the CHOICE.

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 ?
