Work is said to be done when an object is displaced or moved from one place to another by the application of force.
Radha pushed a heavy table but failed to move it. Which of the followi...
Explanation:
Energy and work are related concepts in physics. Energy is the ability to do work and work is the transfer of energy from one object to another.
In this case, Radha pushed a heavy table but failed to move it. This means that the table did not move and therefore no work was done.
However, Radha spent some energy in pushing the table. Energy is spent when a force is applied to an object, even if no work is done.
Therefore, option B is the correct answer: Energy is spent but work is not done.
To summarize:
- Work is the transfer of energy from one object to another.
- Energy is spent when a force is applied to an object, even if no work is done.
- In this case, Radha spent some energy in pushing the table but no work was done because the table did not move.
