two charged particles of mass m and 2m have charges +2q and +q respectively. they are kept in a uniform electric field far away from each other and then allowed to move for some time t . find the ratio of their kinetic energy
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?
A meter stick held vertically with one end on the floor and is allowed to fall. The speed of the other end when it hits the floor assuming that the end at the floor does not slip is ?

(Irodov). A particle moves along the x axis according to the law x
= a cos wt. Find the distance that the particle covers during the
time interval from t = 0 to t.
