A simple pendulum hanging from the ceiling of a stationary lift has a time period $T_1$. When the lift moves downward with constant velocity, the time period is $T_2$, then
  • A${T_2}$ is infinity
  • B${T_2} = {T_1}$
  • C${T_2} < {T_1}$
  • D${T_2} > {T_1}$

    A particle performs $S.H.M.$ of amplitude $A$ with angular frequency $\omega$  along a straight line. Whenit is at a distance  $\frac{{\sqrt 3 }}{2}$ $A$  from mean position, its kinetic energy gets increased by an amount $\frac{1}{2}m{\omega ^2}{A^2}$  due to an impulsive force. Then its new amplitude becomes

    A block of mass $2\,kg$ is attached with two identical springs of spring constant $20\,N / m$ each. The block is placed on a frictionless surface and the ends of the springs are attached to rigid supports (see figure). When the mass is displaced from its equilibrium position, it executes a simple harmonic motion. The time period of oscillation is $\frac{\pi}{\sqrt{x}}$ in SI unit. The value of $x$ is $..........$
