The empty cup burns immediately as its ignition temperature is reached easily. The paper cup containing
water does not burn immediately as the heat supplied to the cup gets transferred to water via conduction which prevents paper from reaching its ignition temperature. Thus, the water in the cup starts boiling when continued to heat for some more time.

Non-contact forces:
Non-contact forces are forces that can act on an object without physically touching it. These forces can act over a distance and do not require direct contact between the objects involved.
Magnetic, electrostatic, and gravitational forces:
- Magnetic, electrostatic, and gravitational forces are examples of non-contact forces.
- These forces can act on objects from a distance without the need for physical contact.
- For example, magnetic forces can attract or repel objects without direct touch, electrostatic forces can cause objects to be attracted or repelled based on their electric charge, and gravitational forces act between any two objects with mass regardless of physical contact.
Explanation of the answer:
In the given question, the statement mentions magnetic, electrostatic, and gravitational forces. These forces are all non-contact forces as they can act on objects without the need for direct contact. Therefore, the correct answer is option B - non-contact forces.
