Question

what kind of force is involved in writing on paper? field force contact force

Explanation:

To determine the force involved in writing on paper, we analyze the two types of forces:

• Field force: Acts at a distance (e.g., gravitational, magnetic). Writing on paper does not involve a force acting at a distance.
• Contact force: Requires physical contact between objects. When writing, the pen (or writing instrument) is in direct contact with the paper, and the force (friction, to be precise, which is a type of contact force) allows the ink or lead to leave a mark on the paper. Thus, the force involved is a contact force.

Answer:

B. contact force (assuming the options are labeled as above, with "field force" as one option and "contact force" as the other; the correct one is "contact force").
