Two blocks of masses m1, and m2 connected by a light vertical spring of stiffness k, m2 kept on a smooth horizontal surface . What should be the initial compression of the spring so that the system will be about to break off the surface, after releasing the block m1?
a small ball of mass 1kg and a charge 2/3 uC is placed at the center of a uniformly charged sphere of radius 1m and charge 1/3 mC. a narrow smooth horizontal groove is made in the sphere from centre to surface as shown in figure. the sphere is made to rotate about its vertical diameter at a constant rate of 1/2pi revolutions per second. find the spedd w.r.t ground with which the ball slide out from the groove. neglect any magnetic force acting on ball?
