Due to some force F₁ a body oscillates with period (4/5) s and the due to other force F₂ it oscillates with period 3/5s. if both the forces acts simultaneously new period will be

A block of mass  100 g attached to a spring of stiffness 100 N/m is lying on a frictionless floor as shown. The block is moved to compress the spring by  10 cm and released. If the collision with the wall is elastic the time period of motion is:

A body of mass 'MM' when hung on a spiral spring, the spring stretches by 20 cm, when it is pulled down and released its period of oscillation is

A particle follows two SHM's. One along the y axis and the other along the x axis.What is the trajectory of the particle of combined SHM's. If A₁≠A₂ and ϕ= π/2 the nature of path followed by the particle is

If a particle is executing SHM on a straight line. A and B are two points at which its velocity is zero. It passes through a certain point P (AP

It is cut into three parts with lengths in the ratio 1:2:3 and connected to the mass in a particular combination so that its time period is halved, what is that combination?

The time periods of oscillation of two simple pendulums are 1 sec, 1.2 sec. Initially both are in same phase of oscillation. The minimum number of oscillations made by longer pendulum when they are again in same phase is:

Force acting on a block is F =(−4x+8)=. Here F is in Newton and xx the position of block on x-axis in meters_________

The change in the length of a simple pendulum of length 1m, when its period of oscillation changes from 2s to 1.5s is:

The displacement of a particle of mass 3 gm executing simple harmonic motion is given by y=3sin(0.2t) in SI units. The kinetic energy of the particle at a point which is at a distance equal to 1/3 of its amplitude from its mean position is
