List of top Physics Questions on work, energy and power asked in TS EAMCET

A tank of height \(5\,m\) is completely filled with water and a cube of side \(1\,cm\) and density \(1.5\,g\,cm^{-3}\) is placed at the bottom of the tank. The work to be done to lift the cube at the bottom to a height of \(15\,m\) above the surface of water is:

If a force of $(6\sqrt{3}\hat{i}-4\sqrt{2}\hat{j})\text{ N}$ acts on a body of mass 3.7 kg and displaces the body by $(2\sqrt{3}\hat{i})\text{ m}$, then the work done by the force is:}

If the kinetic energy of a body moving with a velocity of $(2\vec{i}+3\vec{j}-4\vec{k})$ ms$^{-1}$ is 87 J, then the mass of the body is

The work done in displacing a particle from $y=a$ to $y = 2a$ by a force $F = -\frac{K}{y^2}$ acting along y-axis is

A body of mass 500 g is falling from rest from a height of 3.2 m from the ground. If the body reaches the ground with a velocity of 6 ms⁻¹, then the energy lost by the body due to air resistance is (Acceleration due to gravity = 10 ms⁻²)
