Which one of the following is an example of mechanical potential energy?
Which one of the following is an example of mechanical potential energy?
Activated neuron
Polarized cell membrane
Stretched tendon
Relaxed muscle
The Correct Option is C
Solution and Explanation
The question asks for an example of mechanical potential energy. Mechanical potential energy is the energy stored in an object due to its position or state that has the potential to do work.
Let's evaluate each option:
| Option | Evaluation |
|---|---|
| Activated neuron | Involves electrical activity, not mechanical potential energy. |
| Polarized cell membrane | Relates to electrical potential across the membrane, not mechanical. |
| Stretched tendon | The stretch stores mechanical potential energy, as it involves deformation and has the potential to do work upon release. |
| Relaxed muscle | Does not store mechanical energy, as it is in a relaxed state. |
Based on this evaluation, the correct answer is: Stretched tendon, as it is a classic example of mechanical potential energy, storing energy when deformed.

- An organization allows its employees to work independently on consultancy projects but charges an overhead on the consulting fee.
The overhead is 20% of the consulting fee if the fee is up to ₹5,00,000.
For higher fees, the overhead is ₹1,00,000 plus 10% of the amount by which the fee exceeds ₹5,00,000.
The government charges a Goods and Services Tax (GST) of 18% on the total amount (i.e., the consulting fee plus the overhead).
An employee of the organization charges this entire amount — that is, the consulting fee, overhead, and tax — to the client.
If the client cannot pay more than ₹10,00,000, what is the maximum consulting fee that the employee can charge?
