Two identical straight wires are stretched so as to produce 6 beats/s when vibrating simultaneously. On changing the tension slightly in one of them, the beat frequency remains unchanged. Denoting by the higher and the lower initial tension in the strings, then it could be said that while making the above changes in tension

One end of a spring of negligible unstretched length and spring constant is fixed at the origin a point particle of mass carrying a positive charge is attached at its other end. The entire system is kept on a smooth horizontal surface. When a point dipole pointing towards the charge is fixed at the origin, the spring gets stretched to a length I and attains a new equilibrium position (see figure below). If the point mass is now displaced slightly by from its equilibrium position and released, it is found to oscillate at frequency . The value of is ______
