I have been planning to buy a new car and one of the major considerations for me is the fastest way to make a U turn on a horizontal road at constant speed. Suppose to make a 180^(@) turn on a circular path. The car's steering system does not allow a radius of less than 5m. The road is wide enough to allow a circle of maximum radius of 20m. If the acceleration is greater than 5 m//s^(2), the car skids. The maximum constant speed at which I can take a U turn is :

1.	I have been planning to buy a new car and one of the major considerations for me is the fastest way to make a U turn on a horizontal road at constant speed. Suppose to make a 180^(@) turn on a circular path. The car's steering system does not allow a radius of less than 5m. The road is wide enough to allow a circle of maximum radius of 20m. If the acceleration is greater than 5 m//s^(2), the car skids. The maximum constant speed at which I can take a U turn is :
Answer» `5 m//s` `(10)/(3) m//s` `10 m//s` `15 m//s` SOLUTION :`(v_("max")^(2))/(r_("max"))=5` `v_("max")=10m//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 ?
A concave lens with equal radius of curvature both sides has a focal length of 12 cm. The refractive index of the lens is 1.5. How will the focal length of the lens change if it is immersed in the liquid of refractive index 1.8 ?
