A student compresses a block of elastic material between two plates and measures its total thickness for different applied forces. The block is not inelastically deformed. The readings are within the range in which force and compression are directly proportional.
| Force in N | Total thickness in m |
|---|---|
| 2.0 | 0.068 |
| 6.0 | 0.044 |
Calculate the total thickness of the block when the applied force is 0 N.
A student claims that doubling the applied force from 2.0 N to 4.0 N would halve the total thickness of the block.
Evaluate the student's claim.
