Question

given an example where work done by force is negative​

Answer 1

NEGATIVE WORK:The work done is said to be negative work when force and displacement are in opposite direction. example: When an object is thrown upwards,the force CTS in downward direction whereas displacement acts in upward direction.

Answer 2

Answer:

If the force has a component in the direction opposite to the displacement, the force does negative work.

Example:

If a ball is thrown in upwards direction, its displacement would be in upwards direction but the force due to earth's gravity is in the downward direction
