A body is thrown up with a velocity 10% more than the escape velocity

1.	A body is thrown up with a velocity 10% more than the escape velocity v_(e ). When the body escapes the gravitational pull of the earth the velocity still left in the body is :
Answer» `0.1v_(e )` `0.229 v_(e )` `0.458 v_(e )` `0.20 v_(e )` . Solution :`V=v_(e )+(10)/(100)v_(e )=(11)/(10)v_(e )` `therefore` Velocity of BODY after escaping the gravitational fieldis `v=SQRT(x^(2)-1) "" v_(e )=sqrt(((121)/(100)-1))-v_(e )=sqrt((21)/(100))v_(e )` `=0.458 v_(e )` So CORRECT choice is (c ).

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 ?
