Sample questions

1. 1.Assertion: When the force retards the motion of a body, the work done is zero. Reason: Work done depends on angle between force and displacement.
   • A.Both assertion and reason are true and reason is the correct explanation of assertion.
   • B.Both assertion and reason are true but reason is not the correct explanation of assertion.
   • C.Assertion is true but reason is false.
   • D.Assertion is false but reason is true.
2. 2.The SI unit of work is joule. It is expressed in terms of mass, length and time as
   • a.$\mathrm{kg\,m^2\,s^{-2}}$
   • b.$\mathrm{kg^2\,m^2\,s^{-2}}$
   • c.$\mathrm{kg\,m^2\,s^{-3}}$
   • d.$\mathrm{kg\,m^2\,s^{-2}}$
3. 3.Assertion: Work done by or against gravitational force in moving a body from one point to another is independent of the actual path followed between the two points. Reason: Gravitational forces are conservative forces.
   • A.Both assertion and reason are true and reason is the correct explanation of assertion.
   • B.Both assertion and reason are true but reason is not the correct explanation of assertion.
   • C.Assertion is true but reason is false.
   • D.Assertion is false but reason is true.
4. 4.Calculate the power of a pump which can lift $400\,\mathrm{kg}$ of water to store it in a water tank at a height of $19\,\mathrm{m}$ in $40\,\mathrm{s}$. (Take $g = 10\,\mathrm{ms}^{-2}$)
5. 5.A car is running at a speed of 15 km h⁻¹ while another similar car is moving at a speed of 30 km h⁻¹. Find the ratio of their kinetic energies.
