A block of mass m is slowly lowered from a point where it just touches a vertical fixed spring of stiffness k, till it remains stationary after the applied force is withdrawn. Find the work done by the external agent(a) in compressing the spring by a distance x and (b) bringing the block to its stable equilibrium position.

In a free space, a thin rod carrying uniformly distributed negative charge -q is placed symmetrically along the axis of a thin ring of radius R carrying uniformilly distriburted charge Q. the mass of rod is m and the length is l= 2R. The ring is fixed and the rod is free to move . the rod is displaced slightly along the axis of the ring and then released . find the period T of the small amplitude oscillations of the rod.

Two balls of charges q1 and q2 initially have a velocity of the same magnitude and direction. After a uniform electric field has been applied for a certain time. The direction of the first ball changes by 60∘ and the velocity magnitude is reduced by half. The direction of velocity of the second ball changes by 90∘ . In what ratio will the velocity of the second ball change? Determine, the magnitude of the charge to mass ratio of the second ball if it is equal to α1 for the first ball. Ignore the electrostatic interaction between the balls.
