System shown in figure is released from rest . Pulley and spring is mass less and friction is absent everywhere. The speed of 5kg block when 2kg block leaves the constant of with ground is (force constant of spring k=40N/mandg=10m/s2)
A pump motor is used to deliver water at a certain rate from a given pipe. To obtain 'n' times water from the same pipe in the same time by what amount (a) the force and (b) power of the motor should be increased ?
In figure, the variation of potential energy of a particle of mass m=2kg is represented w.r.t its x-coordinate. The particle moves under the effect of the conservative force along the x-axis. Which of the following statements is incorrect about the particle?
